Consistent with our strategy, we're executing a robust portfolio of midstream growth projects with attractive returns. These new projects will provide us with continued future earnings growth. During the quarter, we announced joint ventures to construct the Liberty and Red Oak crude oil pipeline systems. These projects are backed by long-term volume commitments.

The Liberty pipeline will provide transportation from the growing Rockies and Bakken production areas to Cushing, Oklahoma. Liberty will have access to the Gulf Coast via the Red Oak pipeline. We own a 50% interest and will construct and operate Liberty.

The Red Oak pipeline system will connect Cushing and the Permian Basin to multiple locations along the Gulf Coast, including Corpus Christi, Ingleside, Houston and Beaumont. We own a 50% interest and we'll operate Red Oak. Both pipelines are in supplemental open season seeking additional commitments with limited remaining capacity. The pipelines are targeted to begin initial service in the first quarter of 2021. Phillips 66 Partners continues to construct the Gray Oak pipeline The 900,000 barrel per day pipeline will transport crude oil from the Permian and Eagle Ford to the Texas Gulf Coast, including our Sweeny Refinery.

We received all major permits, acquired all right away and installed 80% of the pipe. The project remains on track to start up in the fourth quarter of this year. Phillips 66 Partners owns 42.25% interest in the joint venture. Gray Oak will connect with multiple refineries and export facilities in the Corpus Christi area, including the South Texas Gateway Terminal in which PSXP own's a 25% ownership. The terminal will have two deepwater docks, 7 million barrels of storage capacity and up to 800,000 barrels per day of throughput capacity. The terminal is expected to start up by mid 2020.

With Liberty, Red Oak, Gray Oak and our existing network of pipelines, we will serve all the key shale oil producing regions with connectivity to the major Gulf Coast market centers. Our pipeline network is integrated with our Central Corridor and Gulf Coast refineries as well as our Beaumont and South Texas Gateway export terminals. We believe this integration is a competitive advantage that further enhances the value across our portfolio.

We continue to expand the Sweeny hub to meet increasing domestic NGL production and global market demand. We're moving forward with construction of fourth fractionator that will have 150,000 barrels per day of capacity and is expected to cost approximately $500 million. Frac 4 is backed by customer commitments and is expected to be completed in the second quarter of 2021. Construction of Fracs 2 and 3 is progressing well and we're on track to start up in the fourth quarter of 2020. Upon completion of Frac 4, the Sweeny Hub will have 550,000 barrels per day of fractionation capacity.

In connection with our expansion at the Sweeny Hub, PSXP is increasing storage capacity at Clemens Caverns from 9 million barrels to 15 million barrels. Completion of the expansion is expected in the fourth quarter of 2020. Also at the Sweeny Hub, PSXP will construct a 16-inch ethane pipeline from Clemens Caverns to Gregory, Texas. The C2G pipeline will serve petrochemical customers in the Corpus Christi area. The pipeline will have 240,000 barrels per day of capacity and is expected to be complete in mid-2021.

In Chemicals, CPChem is expanding its strategic partnership with Qatar Petroleum to develop petrochemical assets in the US Gulf Coast and in Qatar. Pending final investment decisions, these projects will add world-scale ethylene and high-density polyethylene in advantaged feedstock locations with access to global markets. This further enhance CPChem's leading polyethylene position despite the world's growing demand for polymers.

In refining, Phillips 66 Partners recently completed construction of the 25,000 barrel per day isomerization unit at the Lake Charles refinery. That will increase production of higher-octane gasoline blend components. This unit is expected to reach full production in the third quarter.

At the Sweeny refinery, we are upgrading the FCC to increase production of higher valued petrochemical feedstocks and higher octane gasoline. This project is on track to complete in the second quarter of 2020.

This morning, we announced the elimination of incentive distribution rights at PSXP. This transaction improves PSXP's cost of capital, simplifies its capital structure and further aligns the GP and LP economic interest. Our ownership in PSXP increased to 75% after the transaction closes. We believe the transaction is attractive for both Phillips 66 shareholders and PSXP unit holders. PSXP is a premier MLP and it remains a key component of our midstream growth strategy.

So before I turn the call over to Kevin, we'd ask that you hold the date, November 6 for an Analyst and Investor Day we'll be hosting in New York City. With that, Kevin, you can go through the financials.

Kevin J. Mitchell -- Executive Vice President, Finance and Chief Financial Officer

Thank you, Greg. Hello, everyone. Starting with an overview on slide four, we summarize our second quarter financial results. Adjusted earnings were $1.4 billion or $3.02 per share. Operating cash flow including working capital was $1.9 billion. Capital spending for the quarter was $631 million, including $408 million on growth projects. We returned $861 million to shareholders through $406 million of dividends and $455 million of share repurchases. We ended the quarter with 449 million shares outstanding.

Moving to slide five. This slide highlights the change in pre-tax income by segment from the first quarter to the second quarter. During the period, adjusted earnings increased $1.2 billion, mostly driven by refining. All segments had improved results. The second quarter adjusted effective tax rate was 20%.

Slide six shows our midstream results. Second quarter adjusted pre-tax income was $423 million, an increase of $107 million from the previous quarter. This quarter, we achieved strong results in the midstream segment, driven by record pre-tax income in both the transportation and NGL businesses. Transportation adjusted pre-tax income was $245 million, up $42 million from the previous quarter due to higher volumes on our wholly owned and joint venture pipelines and terminals.

NGL and Other adjusted pre-tax income increased $53 million, driven by higher margins and volumes at the Sweeny Hub as well as improved butane trading results. The Sweeny Hub had record earnings and strong operations during the quarter. The LPG export facility loaded a record number of cargoes and the Sweeny fractionator achieved utilization of 118%. DCP Midstream adjusted pre-tax income of $35 million in the second quarter is up $12 million from the previous quarter due to favorable hedging impacts.

Turning to chemicals on slide seven. Second quarter adjusted pre-tax income for the segment was $275 million, $48 million higher than the first quarter. Olefins and Polyolefins adjusted pre-tax income was $260 million, up $41 million from the previous quarter. The increase reflects higher polyethylene margins, driven by lower NGL feedstock costs as well as lower utility costs related to falling natural gas prices. Global O&P utilization was 95%. Adjusted pre-tax income for SA&S increased $8 million following first quarter turnaround activity. During the second quarter, we received $190 million of cash and distributions from CPChem.

Moving to Refining. The chart on slide eight provides a regional view of the change in Refining's adjusted pre-tax income. Refining's second quarter adjusted pre-tax income was $983 million up $1.2 billion from last quarter. The increase was mostly due to higher realized margins and volumes. Realized margins for the quarter increased 57% from $7.23 per barrel to $11.37 per barrel, driven by higher gasoline cracks. Crude utilization was 97% compared with 84% in the first quarter. The first quarter was impacted by significant turnaround activity as well as unplanned downtime. The second quarter clean product yield was 84% and pre-tax turnaround costs were $67 million.

Slide nine covers market capture. The 3:2:1 market crack for the second quarter was $15.24 per barrel, compared to $9.77 per barrel in the first quarter. Our realized margin was $11.37 per barrel and resulted in an overall market capture of 75%. Market capture was impacted by the configuration of our refineries. We make less gasoline and more distillate than premised in the 3:2:1 market crack. During the quarter, the gasoline crack increased 169%, while the distillate crack decreased 8%. Losses from secondary products of $1.35 per barrel increased $0.72 per barrel from the previous quarter due to declining NGL prices relative to crude, partially offset by improved coke margins.

Our feedstock advantage of $0.01 per barrel declined $2.07 per barrel from the prior quarter due to narrowing crude differentials. The other category reduced realized margins by $0.21 per barrel in the second quarter. This was improved $3.52 per barrel from the prior quarter, with the largest driver being clean product realizations.

Moving to Marketing and Specialties on slide 10. Adjusted second quarter pre-tax income was $353 million, $148 million higher than the first quarter. Marketing and Other increased $156 million from higher domestic and international margins, associated with falling spot prices during the quarter. Specialties decreased $8 million primarily due to lower lubricant margins. Refined product exports in the second quarter were 187,000 barrels per day. We reimaged approximately 400 domestic-branded sites during the second quarter, bringing the total to approximately 3,300 since the start of our program.

Slide 11 shows the change in cash during the quarter. We started the quarter with $1.3 billion in cash on our balance sheet. Cash from operations was $1.9 billion, which included a $251 million working capital benefit primarily related to inventory draws. During the quarter we funded $631 million of capital spending and returned $861 million to shareholders through $406 million of dividends and $455 million of share repurchases. Our ending cash balance was $1.8 billion.

This concludes my review of the financial and operating results. Next, I'll cover a few outlook items for the third quarter. In Chemicals, we expect the global O&P utilization rates to be in the mid-90s. In Refining, we expect the third quarter crude utilization rate to be in the mid-90s and pre-tax turnaround expenses to be between $150 million and $180 million. We anticipate Corporate and Other costs to come in between $210 million and $240 million pre-tax.

With that, we'll now open the line for questions.

Questions and Answers:

Operator

Thank you. We will now begin the question-and-answer session. [Operator Instructions] Neil Mehta from Goldman Sachs. Please go ahead, your line is open.

Neil Mehta -- Goldman Sachs -- Analyst

Good morning, team.

Greg C. Garland -- Chairman and Chief Executive Officer

Good morning, Neil.

Kevin J. Mitchell -- Executive Vice President, Finance and Chief Financial Officer

Good morning, Neil.

Neil Mehta -- Goldman Sachs -- Analyst

Good morning. The first question I had was, when I think about your CPChem business, historically you've been -- you've grown this business organically. And you've announced a couple of really good projects here, one in Qatar, one in the Gulf Coast that kind of reinforces that historical strategy. There's been some press reports that the potential for you guys to do a large step-out type of transaction here, which I guess would be inconsistent with the historical way you have grown this business. So without asking you to kind of speculate here, anything you could do to sort of -- to clarify the way you think about building this business would be helpful for investors when we think about it?

Greg C. Garland -- Chairman and Chief Executive Officer

Great, Neil. Well, first of all, as a practice we just don't comment on market rumors or speculation. And even outside of chemicals when you step back and think across our entire portfolio, we followed an organic path over the last seven years. Where we've done things inorganically has been on the asset side. And so think about the Beaumont Terminal or the River Parish or SCOOP/STACK or Plains. So we have been opportunistic on the in organic side from time to time. For us anything we would do inorganically would have to eventually compete with the returns, we can generate on the organic side. And as you read the reports this morning, we have a really strong portfolio of organic opportunities. And so, I'll just leave it at that. I think we're like everyone we look at everything that's out there. We struggle to find things that we think that are accretive to returns, but we'll continue to look.

Neil Mehta -- Goldman Sachs -- Analyst

All right. Fair enough. And then a follow-up question is just NGLs have certainly come under a lot of pressure. And when we think about PSX on a consolidated level with all the moving pieces recognizing you have DCP and there's some element of product -- NGL product yield that comes off your refiners that you have a large ethane-consuming business and your chemicals business, how should we think about the company on a consolidated basis? Do you do better, if NGL prices are lower?

Greg C. Garland -- Chairman and Chief Executive Officer

Well, I would start -- we're a net buyer of ethane at CPChem, so, I mean, low ethane prices definitely benefit our chemicals business. The lower propane prices given our export position and the strong arcs we're seeing particularly to Asia today, that's a benefit for us on the LPG export side. There is impacted DCP across the DCP portfolio to lower NGL prices. So -- but on balance, we have offsetting across the portfolio.

Kevin J. Mitchell -- Executive Vice President, Finance and Chief Financial Officer

I would say within the PSX and PSXP portfolio, many of those pipes and fractionators are fee-based, so we benefit from growing volumes, but not really exposed on the commodity side. With regard to DCP they've been successful converting some of their historical commodity price contracts to more fee-based contracts and they're hedged against the majority of their remaining exposure.

Doug Terreson from Evercore ISI. Please go ahead, your line is open.

Doug Terreson -- Evercore ISI -- Analyst

Congratulations on your results, guys.

Greg C. Garland -- Chairman and Chief Executive Officer

Thanks, Doug.

Doug Terreson -- Evercore ISI -- Analyst

In refining and marketing, Phillips 66 seems to be consistently outperforming peers due to several factors one of which may be higher volume. And on this point, one of your peers suggested recently that US product demand may be exceeding government estimates and that positive revisions to demand may be forthcoming. So I wanted to see whether you share that view and to get your overall outlook for products demand in the US and export markets too, please?

Jeff Dietert -- Vice President, Investor Relations

Yeah, I think when you look at the US consumer, he is in pretty good shape low unemployment, healthy wage growth, consumer confidence, he's in good shape. We saw gasoline demand may be down slightly in the first quarter but it rallied and was up in the second quarter. The vehicle miles traveled up strong in April and up again in May. And so I think demand we're seeing is kind of flattish on the gasoline side year-to-date and what we expect in the back half of the year. On the diesel demand-side, we see it flat to slightly up and that's compared to very tough comps with 2018 diesel demand being up 6% year-on-year. So still very healthy demand on the diesel side as well.

I think as we went through the quarter and some of the flooding in the Mississippi River delayed and some of the planting there was -- the industry did finish strong. And so what we thought was going to be a loss of 70,000 or 80,000 barrels a day of demand in the planting season, maybe it was closer to 30,000 or 40,000 barrels a day. So that's been a little bit better than was feared.

Doug Terreson -- Evercore ISI -- Analyst

Okay. Good summary, Jeff. And then in midstream it seems like there are a lot of share related takeaway export and processing projects planned by the industry, even though shale output growth is decelerating and future spending may have to decline further if E&Ps want to sustain current returns valuation and share prices. And, of course, if we were to ever have consolidation, E&P spending in output would be pressured over the medium term too. So my question is how does the company think about and manage the risk for scenarios such as this one such that perspective returns on investment in midstream are protected?

Greg C. Garland -- Chairman and Chief Executive Officer

Well, I mean we start with partnering, so you see these big pipes, we've got partners in these pipes, strong partners. Secondly, when you look at the volume commitments, throughput commitments these are 7 to 10-year commitments with strong investment grade parties. And so that's the way we try to mitigate the risk, Doug.

Doug Terreson -- Evercore ISI -- Analyst

Okay. Thanks a lot, Greg.

Greg C. Garland -- Chairman and Chief Executive Officer

You bet.

Operator

Phil Gresh from JP Morgan. Please go ahead, your line is open.

Phil Gresh -- JP Morgan -- Analyst

Yes. So, Greg it's been quite an active couple of months here for PSX with all these projects announcements in midstream and chemicals. So, I can certainly see why you signed for another Analyst Day to dive into that. But in advance of that event, I was hoping you could talk about what looks like a reaccelerated growth philosophy, especially given where we are in the economic cycle. Obviously, we're a bit late in the cycle. And then perhaps Kevin, if you could help maybe detail out some of the financing plans behind these projects and kind of help us think through how that fits with the 60/40 band over the next couple of years? Thank you.

Greg C. Garland -- Chairman and Chief Executive Officer

Yeah. I'll just start at high level Phil. We recycle cash, we moved from kind of $4 billion to $5 billion to $6 billion to $7 billion. So if you just take the low end of the range at $6 billion and 60% reinvested you're kind of in $3.6 billion capital budget. So I think that we're going to -- within that in any given year, we could probably on balance above/or below that. Certainly you've seen the past where we didn't have investable opportunities we pull capex way down. We like the suite of projects that we have. They're all very attractive returns and we think build value across the portfolio. So just from that standpoint I think we're consistent with what we've been saying for the past seven years in terms of kind of the 60/40 investment return to shareholders kind of paradigm that we've been in. And we're comfortable with that. We think it's about right for the company.

As we've talked in the -- in Doug's question, we tried to mitigate the risk on these projects, certainly, by taking on partners, looking at volume commitments with good counterparties on the other end of that. Kevin will speak to the project financing. That's another way we use to de-risk these projects. So on balance, I think, we're positive about the organic profile that we have. We're positive about the cash generation of the company. We still think that the first dollar cash we generate is going to go to sustaining capital as $1 billion a year. Second, dollar is going to go to our dividend as $1.6 billion. And then, we have options, but certainly, we can be within $1.5 billion to $2.5 billion in terms of our growth to $1.5 billion to $2.5 billion in terms of our share repurchases, and we can make that all fit within the existing cash flow. And Kevin, I'll let you talk to the project financing.

Kevin J. Mitchell -- Executive Vice President, Finance and Chief Financial Officer

Yeah. Thanks. So just walking through a couple of these projects. Gray Oak, as we talked about in the past, we had communicated our intention to finance that and we closed on the financing in the second quarter. So that's $1.3 billion facility is in place and should effectively cover most of the remaining capex spend this year on that project. The Liberty and Red Oak pipelines, so on a gross basis, the numbers we put out there combined those two projects, that's just over $4.1 billion of capex. We are 50% in each of them. And while we haven't gone down the full project financing path yet, we've structured those projects to where they will be financeable, and it would be our intention to put project-level financing in place on those joint ventures also.

And then the other one, I'll just comment on is -- well, actually two more. So, also in Midstream, so we're constructing the -- you've got Fracs 2 and 3 under construction. We just sanctioned Frac 4. Those are all being funded by us, so no financing in place on those projects. And that spend comfortably fits within the overall capital allocation framework, as Greg just outlined. And then just lastly on chemicals. So the two projects that were announced, bear in mind that these are not FID level yet, so there's still a ways to go. But given the structure with it, these being partnerships at the CPChem level, they should be amenable to financing. Now, the reality is, you've got four parties and each with align around those funding plans. So within QP, CPChem, us and Chevron need to align around that. But they should be structured in a way that if the owners are in alignment, then there's potential for financing around those. So, overall, when you put all this together, this still very much works in the context of our overall capital allocation framework.

Phil Gresh -- JP Morgan -- Analyst

That's very helpful. And just to clarify, Kevin. When you say project financing at the CPChem level, should we be thinking of some combination of free cash flow at the entity, plus maybe raising some debt there, plus maybe even project financing at the CPChem level?

Kevin J. Mitchell -- Executive Vice President, Finance and Chief Financial Officer

Well, the reality is, it could be any or all of the above. So you have the potential at the project level. So if you take the Qatar project, or you take the Gulf Coast project, you have the potential to do two sort of projects level financing at that point. But there's also be potential for CPChem at the CPChem entity level to take on debt. They have a very strong balance sheet and so they have that capability as well. But all of these things require the sort of owner alignment around path forward on funding.

Phil Gresh -- JP Morgan -- Analyst

Okay, great. And then just my follow-up would be to Neil's question, maybe more specifically on the refining business. Is there any additional disclosure you could provide around your exposure to products and NGLs and naphtha propylene and the like. I know others have been talking about it. And unless, I missed it I haven't seen any specific disclosure with your exposures there to help kind of think through the moving pieces? Thanks.

Jeff Dietert -- Vice President, Investor Relations

Yeah. So as we go through our secondary products, Kevin summarized it in the opening remarks. But when you look at the products that are there really naphtha is de-minimis within our refining products. NGL yield is about 4%. Coke yield about 4% and fuel oil yields between 2% and 3%. So those are the primary products. There are a lot of smaller products that are included in there as well, but that would give you a high level of our exposures to individual products within the secondary product category.

Operator

Doug Leggate from Bank of America Merrill Lynch. Please go ahead, your line is open.

Doug Leggate -- Bank of America Merrill Lynch -- Analyst

Thank you. Good morning everybody. Greg, I don't want to front-run the November Analyst Day too much here, but it seems that the EBITDA mix of the company is going through another bit of a fairly rapid evolution as it relates to de-emphasizing refining. I'm just wondering if that read is correct, how should we think about the mix shift as we go forward and with a list of projects you've got right now in the mid-cycle basis where do you see refining stacking up relative to the rest of the portfolio?

Greg C. Garland -- Chairman and Chief Executive Officer

Well, if you just kind of look at averages kind of 12 to 18. Refining is about $4 billion of EBITDA. Our midstream business is now about $2 billion. Our Marketing and Specialties is at $1.4 billion. Our distributions from CPChem about $1.2 billion. So when you think about $800 million of corporate and interest and then $1 billion or so of taxes that gets you to kind of that $6.5 billion of cash flow that we've been talking about. So that's kind of how we think about the portfolio. Certainly, we've made investments in the refining business, but they've been quick payout kind of lower capital items that we've chosen to invest in. For instance, upgrading the FCCs, upgrading our billings of vacuum tower and though we generated a couple of hundred million dollars of EBITDA on our refining business through these investments. And we still have probably in the next three years another $300 million to $400 million of EBITDA coming our way from the investments we're making in refining. On the midstream side, if you want to look all the way through 2021, there's probably $800 million to $900 million of EBITDA coming in on the midstream business. So the strategy around growing our midstream, growing our chemicals business and investing smartly in our refining business has been the strategy over the last seven years and we're really not departing from that.

Kevin J. Mitchell -- Executive Vice President, Finance and Chief Financial Officer

I don't know, Jeff, if you want to comment on the topic. Go ahead, Jeff.

Greg C. Garland -- Chairman and Chief Executive Officer

Jeff, give me an A on that.

Kevin J. Mitchell -- Executive Vice President, Finance and Chief Financial Officer

That was a good summary. Go ahead.

Doug Leggate -- Bank of America Merrill Lynch -- Analyst

No I was just going to say so, it looks to us, at least with the list of projects you've got right now before we consider further dropdowns, we're moving well under 50% of the portfolio for refining on a mid-cycle basis. Does that sound reasonable? Once these projects are complete? I mean once you've moved through -- I mean obviously, we haven't got definition on the chemical joint ventures yet. But with what you've got going on in the midstream would it be fair to assume that refining is trending toward under 50% at the corporate mid-cycle EBITDA?

Greg C. Garland -- Chairman and Chief Executive Officer

Yeah. If you're excluding our Marketing and Specialties business from refining, I think that's probably a true statement.

Doug Leggate -- Bank of America Merrill Lynch -- Analyst

Yes, I'm separating that out, right?

Jeff Dietert -- Vice President, Investor Relations

Especially as you think 2020, 2021 time frame.

Doug Leggate -- Bank of America Merrill Lynch -- Analyst

Okay. Thank you for that. My follow-up is actually a little -- I want to kind of, I guess go back a couple of years to some of the questions that used to come up around Tier 3 gasoline. Gasoline has, obviously, been a -- it certainly was our primary basis for being pretty cautious in the space the last couple of years. But it seems to us that with the chatter about potential VGO swing toward bunkers from next year and the three-year runway for Tier 3 gasoline kind of, I guess, coming to an end at the beginning of next year, are there grounds for a little bit more optimism that gasoline actually has some structural positives supporting, maybe offsetting a little bit the alignment of the crude slate there has lifted supply here. I'm just curious on your broader perspective as to whether Tier 3 and VGO issues among perhaps lower utilization rates across the industry can finally put a little bit of support under that market? And I'll leave it there.

Jeff Dietert -- Vice President, Investor Relations

Yeah, I think Tier 3 is an excellent point with the average sulfur content last year at over 20 parts per million and moving to 10 parts per million at the start of next year. The credits that are available -- Tier 2 credits are swelling the gasoline pool somewhat currently. I think as you look at the IMO situation, it's still I think a challenge to figure out exactly how that's going to play out. It doesn't look to us as though there's going to be -- 2 million barrels a day of incremental diesel production to meet that incremental marine fuel market and some is going to have to come from other products and certainly some of that could be VGO. We're struggling to really predict what that percentage would be or how much of that total will be. But it should take some gasoline out of the gasoline pool.

I think with regard to Phillips 66, we're currently producing gasoline with the sulfur content comfortably below where the overall industry is. We are in good shape to meet the Tier 3 standards. The vast majority of the capital spending has already occurred and what little Tier 3 spending is left will fall within the normal range of our sustaining capital spend. When we look at premium gasoline, for example, we're upgrading more gasoline into the premium grade than the industry average and will benefit from a couple of growth projects. One, the 25,000-barrel a day Lake Charles isom unit, which is scheduled to come up this quarter as well as next year Sweeny FCC optimization. Both of them will allow us to increase premium gasoline production.

Operator

Roger Read from Wells Fargo. Please go ahead, your line is open.

Roger Read -- Wells Fargo -- Analyst

Yes, good morning. Thank you. Thanks for the explanation on the gasoline side there, Jeff.

Jeff Dietert -- Vice President, Investor Relations

You've done some nice work on Tier 3 Roger.

Roger Read -- Wells Fargo -- Analyst

Thank you. Thank you. Hoping maybe to change gears a little bit back to the midstream side. Great performance here in the quarter. I think back to when the Sweeny fractionator and the LPG export docks were first talked about, the numbers were pretty big. I'm wondering, when we go back to then, is that what we're now seeing? I mean 118% utilization of the fractionator obviously is a little bit beyond the typical budget. And then, with LPG volume exports at a record, did we get maximum there? I guess, what I'm kind of getting at is, was Q2 in that particular area as good as it gets or is there something else in the tank? And then, as a little extra to that, did we see operating leverage come through here with the additional throughputs and that's what really drove the margins?

Greg C. Garland -- Chairman and Chief Executive Officer

So, I think, in terms of the export facility in the frac, both are running at well above design rates. We're kind of at 200,000 barrels a day across the dock and we've had strong arbs in Asia and we had lower propane prices. So that's driven arbs and the profitability. We've seen dock fees bottom in the kind of the $0.05 to $0.06 range a couple of years ago and they were up in the kind of the low double digits in the second quarter. So you kind of had the -- if you will, the Sweeny Hub running, approaching kind of a $300 million annualized EBITDA run rate, which is at the low end of what we had thought when we approved the project. We thought there'll be some room to play the arb above that and so we had numbers out there as much as $500 million. So we're still underperforming our expectations there, but certainly this is probably the best quarter we've ever had across the frac and the LPG export facility. There is some capacity coming on later this year and next year, but there's also another 1.4 million frac capacity coming on. And so, our view is that, the docks are going to be quite active over the next couple of years, needing to clear the propane to the export markets.

Jeff Dietert -- Vice President, Investor Relations

Yeah. We've seen healthy demand in Asia, new units coming on, widening the arb as well as strong supply domestically, as Greg mentioned. So that arb between the Gulf Coast and Asia, as well as Gulf Coast and Europe, has been widening. The shippers have taken disproportionate share of that but we're seeing some benefit there as well.

Kevin J. Mitchell -- Executive Vice President, Finance and Chief Financial Officer

The one thing I'd add, Roger, as you think about Fracs 2 and 3 coming on in 2020, so next year, that provides some other additional uplift, because we'll be able to essentially fill out the export dock with the LPGs coming off the fracs. And so, we're not going to pay to move propane down from Belvieu and so you get some uplift at that point when those assets are complete.

Roger Read -- Wells Fargo -- Analyst

Okay. Yeah. Thanks. That's really helpful. And then, back to one of the questions earlier, distributions from CPChem. I think, the number was $1.2 billion. As we look at the build-out of the facility in Qatar and in the US and talked about the different financing. But should we think about that $1.2 billion as a pretty good baseline? Obviously, margins, operating levels will impact that, but that's a good baseline. It will be maintained even through the build-out and capex phase of these next two big projects?

Kevin J. Mitchell -- Executive Vice President, Finance and Chief Financial Officer

Yeah. I think that's a reasonable base assumption to use. I mean, you hit the nail on the head that it's very much subject to what the margin environment's looking like, exactly what the spend profile of those two projects is. Remember, it's two major projects, but it's 50% of one and 30% of another. And so, on a cost basis, it's still less than doing one sort of world-scale Gulf Coast project. But for planning purposes, it's probably a reasonable assumption, but recognize there's just going to be a lot of moving parts as we get close to that point in time.

Roger Read -- Wells Fargo -- Analyst

Okay, great. Thanks. I'm looking forward to the Analyst Day and wondering Greg, if you're going to provide us that intrinsic value at the Analyst Day?

Prashant Rao from Citigroup. Please go ahead, your line is open.

Prashant Rao -- Citigroup -- Analyst

Thank you. Good morning and thanks for taking the question. I wanted to touch back on one of the things that, Jeff mentioned in a previous answer about the uncertainty around how IMO 2020 gets resolved and get your views on some indications that we could be seeing commodity spreads and some other indicators that we're getting the first movement of an IMO 2020 sort of impact? Specifically, isom for fuel has been tight but we are seeing time spreads in Asia try to widen out perhaps on the forwards. Storage rates for the high sulfur fuels more announcements of blended new compliant marine fuel. It's a bit early still, but I think we're hitting that window where we were all expecting something to start to emerge in the coming months. But always appreciate your views on this tend to be more moderated and measured. So anything you'd have to share in terms of color would appreciate that [Indecipherable] for me.

Jeff Dietert -- Vice President, Investor Relations

Yes. I think you're hearing more about the different blends. We are taking advantage of our Bartlesville technology center and testing blends there. We're expecting conversion of tanks in the September-ish time frame and expect shippers to be buying compliant fuels in the fourth quarter. I think there are some early indications of compliant marine fuels for CAO 2020, trading at $12 to $15 a barrel over Brent. There's not a lot of liquidity in that market. It's still early. We are starting to see inventories build. I've seen reports of up to 12 VLCCs in Singapore in anticipation of the transition. So I think things are starting to move in that direction. I think it's still early to have a high degree of confidence exactly what impact it's going to have on diesel cracks, on compliant fuel, on high sulfur fuel discounts. But I do see it being a positive for the industry. It does substantially reduce the industry's footprint from an emissions perspective as well.

Prashant Rao -- Citigroup -- Analyst

Thanks. Appreciate that. The other question I have, let's touch back on the agriculture or the Ag exposure, given the weather issues in the quarter and it sounds like there's a strong finish to the quarter there which was nice to see. But wanted to get a sense of, if you can help us think about total exposure for -- economic exposure for Phillips as a consolidated entity there? And then as we think through the back half of the year in 2020, what's been missed in planning this year, one would assume if the pricing was there that would be making up for the planning next year. And so as we look out through the next call it 6, 12, 18 months, can we get a sense of how we should be thinking about the cadence of that and maybe how material or not material, any upside impacts might be?

Jeff Dietert -- Vice President, Investor Relations

I might take the first question. I think with regard to drivers, the global economy is a meaningful driver for product demand in our Refining business. It's a meaningful component to the chemicals business as well. I think with regard to Midstream, the major drivers there are production growth, US shale opportunities there. So I think I would put those as the primary drivers for those three businesses.

Prashant Rao -- Citigroup -- Analyst

I meant -- sorry, just to clarify with specifically with reference to the agricultural exposure, because we were hearing there could be a little bit -- I mean you talked about the constant diesel demand that there was a little bit -- there could have been a little bit of impact on the distillates and fuel side what we are seeing in the US from flooding issues. That didn't appear as much as we'd feared before. I was thinking more specifically about that. Sorry, if I didn't clarify.

Jeff Dietert -- Vice President, Investor Relations

Okay, I apologize. Yeah, so from an industrywide perspective, we were initially looking maybe 70,000 barrels a day and negative impact from the planning season as we were looking midway through or partway through the planning season. And the planning activity picked up at the end more than anticipated. And so I think the closer estimate is something like 30,000 or 40,000 barrels a day and that's industrywide not specific to Phillips 66.

Paul Chang from Scotia Howard Weil. Please go ahead, your line is open.

Paul Chang -- Scotia Howard Weil -- Analyst

Hey, guys, good afternoon.

Jeff Dietert -- Vice President, Investor Relations

Hi, Paul.

Greg C. Garland -- Chairman and Chief Executive Officer

Welcome back.

Jeff Dietert -- Vice President, Investor Relations

Welcome back, Paul.

Paul Chang -- Scotia Howard Weil -- Analyst

Thank you, Jeff. Two questions if I may. One, Greg or Jeff, on the IMO branding to the very low sulfur fuel oil, from Phillips standpoint, are you guys going to use the VGO as a primary ingredient or that you're trying to brand high sulfur fuel oil?

Jeff Dietert -- Vice President, Investor Relations

So one of the challenges with the industry is that this is really kind of a refinery by refinery evaluation. And I think as we look, we've got a number of different alternatives where as you know a high diesel yield portfolio within Refining. We've got another 25,000 barrels a day of diesel coming from projects that are under way. Those projects were justified with economics that didn't include IMO, but they will benefit from wider distillate cracks in an IMO environment. So there's definitely a diesel component to the way that we're approaching marine fuels. I think as we look at the VGO component, we see that as being challenging. Really what you're looking for are heavy barrels resid or diesel barrels that are low in sulfur. The naphtha and light barrels are not -- don't perform well in marine engines. The challenge is that most of your heavy molecules also tend to be sour and most of your light naphtha baste tend to be sweet. And so you're really looking for specific flows of VGO that might make sense in the marine fuel market. And I think those are tough to identify.

Paul Chang -- Scotia Howard Weil -- Analyst

Right. And I presume you guys have looked at the patent out there by Exxon and Shell and I assume that you guys believe you will be able to brand around that and not infringing their patents?

Jeff Dietert -- Vice President, Investor Relations

We have no intention of infringing anyone's patents. We're looking at our own blends and we will be able to participate in that market and our commercial people are open for business there.

Paul Chang -- Scotia Howard Weil -- Analyst

A final one for me. Greg, on CPC you've got that joint venture. I assume, that would mean your own -- the CPC-owned Gulf Coast second ethane cracker went up probably on whole, replaced by debt. Is that a strategic shift in the CPC? That's how, going forward, in terms of the expansion going to look like, or this is really just a one-off deal?

Greg C. Garland -- Chairman and Chief Executive Officer

You're talking about the strategic partnership with Qatar on the Gulf Coast cracker?

Paul Chang -- Scotia Howard Weil -- Analyst

I'm sorry. Yes.

Greg C. Garland -- Chairman and Chief Executive Officer

It was just -- I think it was an opportunity to do two projects and by partnering with a great partner that we've had a long relationship with, we're able to reduce risk, right? And to, share in two projects versus doing one. And we just -- we like the balance of risk from that investment opportunity that was given to us. So rather than picking one or the other, we found a way to do them both.

Manav Gupta from Credit Suisse. Please go ahead, your line is open.

Manav Gupta -- Credit Suisse -- Analyst

Hey, guys. A quick question. I want to focus on the Gulf Coast and specifically the capture on the Gulf Coast. You showed a higher capture quarter-over-quarter on the Gulf Coast. I'm trying to understand what were the drivers of the higher capture. As well as, if you could talk about how much of a role did Bayou Bridge actually play in that higher capture quarter-over-quarter on the Gulf Coast?

Jeff Dietert -- Vice President, Investor Relations

Yeah. So as we look at when 1Q to 2Q, the -- we did have a fair amount of maintenance activity in the Gulf Coast in the first quarter with Lake Charles and Sweeny being down for turnarounds. And so that impacted capture rates. I think with the product pricing, clean product pricing, we saw improvement in the second quarter relative to 1Q as well. As we look at Bayou Bridge, it connects the -- or extends the DAPL pipeline into Beaumont and our facilities there and then Beaumont -- Bayou Bridge brings barrels up from Beaumont into Lake Charles. So that gets access to Lake Charles as domestic and Canadian barrels that are easily accessible by pipeline and we do see a benefit there from a Lake Charles Refining profitability perspective. We've completed the expansion of a Bayou Bridge from Lake Charles to St. James which also opens up the ACE project that we've talked about, which would connect St. James to Clovelly and then into our Alliance Refinery as well. So we're looking forward to trying to keep the project moving forward as well.

Kevin J. Mitchell -- Executive Vice President, Finance and Chief Financial Officer

Manav, it's Kevin. Just -- the big driver in terms of the capture quarter-over-quarter was the turnaround activity in Q1. So a fair amount of activity across the Gulf Coast system in Q1 that you didn't see to near the same extent in the second quarter.

Manav Gupta -- Credit Suisse -- Analyst

Perfect. A quick follow-up is that, I think [Indecipherable] made some comments that Wood River could have done even better because of flooding there were pipeline outages and other problems. I'm just trying to understand, if there's a number in terms of that you can give us as to how much better Wood River could have done had those flooding issues not happened?

Kevin J. Mitchell -- Executive Vice President, Finance and Chief Financial Officer

Yes. That's a true statement. Wood River was impacted by flooding in the quarter. But that's not something we're going to give a sort of what-if type number around.

Justin Jenkins from Raymond James. Please go ahead, your line is open.

Justin Jenkins -- Raymond James -- Analyst

Great. Thanks. Good morning everyone. I guess, I want to start just going back to Doug's question on maybe Midstream risks and even beyond whatever might happen on commodity prices. It does seem like it's just become harder to build pipelines. So maybe just want a sense of your comfort level with the routing plans specifically for Red Oak and Liberty and maybe you might -- how you might address any potential construction issues, if there are any?

Greg C. Garland -- Chairman and Chief Executive Officer

I think certainly there's been many pipelines constructed without an issue. And I think that you get out early and you work with all constituents. Along the route, you pick the best route to go there and so that's what our company does. We'll be obviously executing on Liberty, Plains likely to be executing on Red Oak in terms of the construction. On Gray Oak, I think that the guys doing that, did a great job in terms of -- we're 80% pipes in the ground, it was really had no major issues there along that right of way. So we're expecting that -- these will be executed well and we'll deal with the ssues, if they come up when they come up. But I think part of it is just being living our values every day and working with safety on our commitment in mind with all the folks in all positions along the right of way areas. But we believe, we'll get it done.

Justin Jenkins -- Raymond James -- Analyst

Understood. Appreciate that Greg. And follow-up here is on PSXP here with the IDR issue resolved. Does it change anything in terms of maybe the scope of organic growth that PSXP can pursue or maybe how you're thinking about dropdowns or is this just the next step in evolution here?

Greg C. Garland -- Chairman and Chief Executive Officer

I guess this is the next step in evolution of the MLP. Thinking back over the past 18 months, I don't think I've had a conversation with investors when they haven't encouraged us to do something with the IDRs. And just from a simplification standpoint, structure cost of capital etc. even though we haven't gone to the equity markets since 2017. But if you think about for an LP investor, if we do a 10% return project at PSXP we're effectively getting a 5% return. And so it does impact cost of capital even organic for our LP unitholders. And so we just need to restructure that.

We're trading at 6% to 7% yield and that's kind of 15 times multiple and to the sum of the parts that PSX. We're going to be incented to grow the master limited partnership to the extent that it can. And as you can see we're executing essentially $1.3 billion worth of projects today. And this year, of course, with a project financing that gets cut down toward $700 million in terms of cash out the door. But still we'll put as much growth as we can into PSXP as long as it make sense and the multiples would incent us to do that.

Matthew Blair from Tudor Pickering Holt. Please go ahead, your line is open.

Matthew Blair -- Tudor Pickering Holt -- Analyst

Hey, Greg your Chems business outperformed peers in Q2. What do you think the drivers were behind that? And then also could you share your near-term outlook for US ethane and PE prices just given all the new fracs, crackers and PE plants on deck?

Greg C. Garland -- Chairman and Chief Executive Officer

Well, I think that you kind of look at CPChem's portfolio if you want to think about performance relative to the peers, so assets primarily in the Middle East and in the US, assets that are primarily LPG or ethane-based. And so those margins have certainly been very good relative to say naphtha crackers in Asia or Europe. So it's really the geographic base of the assets. CPChem ran well certainly during the quarter that always helps. In ethane, I can't give you a forecast on the pricing for ethane because it would be wrong. But I would say as we still think there are 600,000, 700,000 barrels a day of ethane rejection. Today we got 1.4 million barrels a day of frac capacity coming on this year and next year. So there will be more ethane available. You also have some projects in start-up mode, although some of them are probably slower than what people have thought. And so we'll just have to put all that together. But our view is that ethane is going to be available out into the next few years. Ethane is going to be attractively priced relative to the heavier feeds globally and that the Middle East and the US Gulf Coast assets will be very, very competitive on the global stage.

Matthew Blair -- Tudor Pickering Holt -- Analyst

Sounds good. And then IHS shows CPChem as net long US ethylene by about 600 KT. Could you talk about, what you do with your excess ethylene today? Is that sold on a contract basis into the domestic market or exported on a spot basis? And would you consider any sort of ethylene derivative projects to reduce the net length?

Greg C. Garland -- Chairman and Chief Executive Officer

Yeah. So we have one of the smaller ethylene units at Sweeny shut down today. So I'd tell you, we get to mid-90s on operate. So our intent would be to bring that unit back up at the appropriate time. Certainly CPChem has the bottleneck opportunities to take care of some of that length out in the future and they have plans on deck to make investments and in terms of the debottlenecks around that olefins, polyolefins, alpha olefins chain that CPChem has today. So we don't look at the length as a big issue. There are some spots sales or contractual sales I should say in the ethylene business from CPChem. But primarily our strategy has been to pair the derivatives with the ethylene capacity over the long-term.

Jason Gabelman from Cowen. Please go ahead, your line is open.

Jason Gabelman -- Cowen -- Analyst

Yeah, hey thanks for taking the question. It looked like equity affiliate distribution cash was a drag on the quarter, or a bit lower at least than we had anticipated. Was there any timing issues there for -- on the distributions from the affiliates in 2Q?

Kevin J. Mitchell -- Executive Vice President, Finance and Chief Financial Officer

Yeah, Jason it's Kevin. Really not, I mean it's -- the equity earnings were $640 million, $648 million, the distributions were just over $500 million. That's not too far off of what you would normally expect. I mean, generally speaking, the -- you would expect the distributions to be a little bit less than the equity earnings, given that those equity affiliates have capex, their own capital programs to fund as well. And so, I don't think there's anything significant there. I think the -- it was a little bit different. I think, you had some disproportionate distributions in the first quarter that head back, go the other way. And so, when we look at this on a year-to-date basis, it's all very reasonable from how we look at the cash flow.

Operator

Thank you. We have now reached the time limit available for questions. I will now turn the call back over to Jeff.
