Octane blending
Overview
Demand for high octane components vary throughout the year depending on seasonality, premium gasoline market share, and refinery performance. Stricter gasoline standards also contribute to demand for high octane components.
Among the list of high-octane components are reformate, alkylate, MTBE, ETBE, toluene, xylenes, ethyl benzene, and others. Some of these components primarily see demand from the chemical market but could be diverted to the gasoline pool if there are returns in that segment.
Each blendstock has specific octane rating and rvp content that determines its value in the gasoline pool. Gasoline blenders will look at market prices for each of the octanes and see how it relates to the value in the gasoline pool. In the summer of 2023, high volumes of ethylbenzene were diverted to the gasoline instead of the production of styrene, as styrene prices fell below ethylbenzene blend value.
MTBE is a high-octane component for gasoline blending, but only used in some countries. MTBE demand has been led by growth in Asia, Middle East, and Latin Markets. Other regions have focused on increased biofuel usage which includes ethanol and ETBE.

Ethane rejection concerns heighten on export block
Ethane rejection concerns heighten on export block
Houston, 6 June (Argus) — US traders and gas producers are mulling over the implications of higher rates of US ethane rejection as the indefinite curtailment of US ethane cargoes to China spurs fears of a supply glut of the feedstock. Exporters Enterprise Products and Energy Transfer , the only waterborne exporters of US ethane, announced on 29 May and 4 June, respectively, that the US Commerce Department's Bureau of Industry and Security (BIS) had ordered them to apply for licenses to export ethane to China. On 4 June, Enterprise reported that emergency license applications for three of its cargoes, totaling 2.2mn bl, had been denied . "News that the [BIS] doesn't intend to issue ethane export permits suggests an increasingly dire situation," said one market participant. US ethane inventories stood at 63.9mn bl in March, the latest data available from the US Energy Information Administration (EIA), up 9.8pc versus last year, when supplies totaled 58.2mn bl. The US produced 2.83mn b/d of ethane from natural gas processing in 2024, according to annual data from the EIA, resulting in a surplus of 500,000 b/d over its domestic petrochemical consumption. Nearly all of this excess is exported, and about 46pc of shipments last year, or 227,000 b/d, went to China. Large-scale exports of the feedstock, which is used in ethylene production at steam crackers, are relatively new. Waterborne exports of ethane began in 2016, and until that time, excess supply that wasn't profitable to fractionate and pipe to storage caverns at Mont Belvieu, Texas, were rejected upstream at processing plants into the natural gas stream. Midstream operators estimated that US ethane rejection clocked in around 500,000 b/d in 2015, when the US produced a little more than a third of the ethane it does today at 1.13mn b/d and consumed only 1.07mn b/d domestically. Some analysts fear higher rates of US ethane rejection going forward could depress natural gas prices. "The recently announced ethane export restrictions to China have raised some concerns over a potential oversupplied domestic market, which could lead to more ethane rejection and create near-term price pressures," on natural gas, RBC Capital Markets analyst Scott Hanold said in a note to investors. An uptick in ethane left in the gas stream also pushes gas operators to potentially contend with a higher calorific content. Natural gas producers have been investing in additional pipeline capacity to accommodate growing demand for LNG exports, however, and the infrastructure is more flexible now than it was back in 2016. "The US exports approximately 250,000 b/d of ethane to China, and that's about 0.4bn cf/d of ethane that would need to be rejected into the US natural gas system," according to Craig Barry, Argus ' lead ethylene consultant. "That should be manageable for US producers, especially as new natural gas egress pipelines come online in the second half of 2025 and into 2026." Short-term pricing From 28 May to 5 June, prompt-month Mont Belvieu, Texas, EPC ethane fell by 19.4pc to 19.25¢/USG, its lowest point since 13 November. Ethane's differential to its fuel value relative to Nymex natural gas at the Henry Hub turned negative on 29 May and remained negative thereafter, troughing at -5¢/USG on 4 June, the steepest discount since 15 December 2022. A flip to rejection by gas producers is typically indicated when ethane enters negative territory relative to its fuel value in spot natural gas in the Permian. Ethane's premium to spot gas prices at the Waha hub in west Texas declined from 12.37¢/USG to 9.4¢/USG across the period, and if Waha prices remain steady, ethane prices would need to halve to enter rejection territory in the Permian. Major operators may also be incentivized, however, to reject ethane into the gas stream at greater rates if prices fall below spot gas on the US Gulf coast, according to market participants, and would need to dip below a milder 17.375¢/USG to turn negative relative to its fuel value in Houston Ship Channel gas, which it sits at its tightest premium to since 4 March at 1.88¢/USG. Steep declines in prompt-month ethane pricing have widened the contango seen along the forward curve, possibly reflecting stronger sentiment once the US trade dispute with China is resolved. The prompt-forward month carry widened to 1.625¢/USG yesterday. June EPC ethane traded at a stronger 21.25-22.5¢/USG Friday morning, and sits at a 2.8¢/USG discount to its fuel value relative to Nymex gas, based on intraday values.

LyondellBasell agrees sale of select assets: Correction
LyondellBasell agrees sale of select assets: Correction
Changes financial figures in third paragraph to € from $ London, 5 June (Argus) — LyondellBasell said it is in exclusive negotiations with Munich-based industrial investment firm Aequita, regarding the sale of four olefin and polyolefin assets in Europe. The deal includes its integrated cracker and polyolefin assets in Berre, France and Muenchmuenster, Germany, and stand-alone polypropylene (PP) sites in Carrington, UK and Tarragona, Spain. The deal is contingent on consultations with local works councils and is expected to close in the first half of 2026. The sites were part of six put under strategic review in May 2024. LyondellBasell's Brindisi PP asset is not part of the deal and its future remains under review. Lyondell Basell confirmed the closure of its Maasvlakte propylene oxide-styrene monomer plant — the final site included in its initial review — in March. The companies said that the package of assets "represent a scaled olefins and polyolefins platform strategically located in proximity to a longstanding customer base and with access and connectivity to key infrastructure". LyondellBasell will contribute €265mn ($303mn) of €275mn total cash funding to support the separated business, but said that the sale would reduce its annual capex by around €110mn, reduce fixed costs by €400mn, and reduce the scope for decarbonisation investments. Decarbonisation of the Berre and Muenchmuenster sites by 42pc of 2020 levels by 2030, as previously committed to by LyondellBasell, would cost hundreds of millions of euros, or more on a faster timescale. Sale of the assets was preferential to closing them, which would incur environmental liabilities, now assumed by Aequita, LyondellBasell said. Aequita is a private equity group focussed on companies in special situations and group carve outs. It has no other chemicals businesses, but other investments include industrial and automotive parts suppliers. Managing partner Christoph Himmel said "Each site brings a strong operational foundation and a highly experienced, committed employee base. We are confident in our ability to accelerate their development". LyondellBasell indicated that it remains committed to Europe, and said the sale will concentrate its European footprint on "economically sustainable sites". Its remaining European assets are centred around two crackers and downstream units in Wesseling, Germany, PP assets in Italy and propylene oxide capacity in France and the Netherlands. Tarragona and Carrington have capacities of 390,000 t/yr and 210,000 t/yr of PP, respectively. Muenchmuenster has capacity of 400,000 t/yr of ethylene, 265,000 t/yr of propylene, 67,000 t/yr of crude C4s and downstream production of 320,000 t/yr of high-density polyethylene (HDPE). Berre has capacity to produce 465,000 t/yr of ethylene, 270,000 t/yr of propylene and 155,000 t/yr of crude C4s. The site at Berre also has downstream capacity for 320,000 t/yr of low-density polyethylene (LDPE), 350,000 t/yr of PP and 80,000 t/yr of butadiene extraction.

Phillips 66 shareholders split board vote
Phillips 66 shareholders split board vote
Houston, 21 May (Argus) — Activist hedge fund Elliott Investment Management is set to win two seats on Phillips 66's board of directors, short of its goal of four seats, according to preliminary results. Two Phillips 66 nominees were also elected in the vote, a positive result for the US refiner and midstream operator. Elliott, which has amassed a $2.5bn stake in Phillips 66, had put forth four nominees for the board in a proxy fight which culminated today at an annual meeting of shareholders. Both sides declared victory after the split vote on the four open seats. Phillips 66 said the vote reflects a belief in its integrated strategy of holding assets in different sectors, while Elliott said the vote "sends a clear message" that shareholders demand meaningful change at Phillips 66. The two Elliott nominees elected to the 14-member Phillips 66 board are Sigmund Cornelius, former chief financial officer of ConocoPhillips and Michael Heim, former chief operating officer of Targa Resources, according to preliminary voting results. The two Phillips 66 nominees elected to the board are Nigel Hearne, a 35-year veteran of Chevron, and Robert Pease, a former Motiva and Cenovus downstream executive who was appointed to the board in 2024 to address Elliott's concerns about a shift in focus from refining to midstream. Phillips 66 also said today that shareholders "overwhelmingly" rejected an Elliott proposal requiring annual director resignations, according to the preliminary results. The voting tally will be tabulated and certified by an independent inspector and final results will be reported to the US Securities and Exchange Commission. The two Elliott nominees for the Phillips 66 board who were not elected are Brian Coffman, former chief executive at Motiva, and Stacy Nieuwoudt, former energy analyst at Citadel. The two Phillips 66 nominees to the board that were not elected are current director John Lowe, who was up for re-election, and Howard Ungerleider, a former Dow president and chief financial officer. Long-running battle over direction Elliott contends that Phillips 66 has consistently trailed its industry peers and needs to streamline operations, including spinning off or selling its midstream business, selling its 50pc stake in Chevron Phillips Chemical (CPChem), and possibly other assets. Elliott has waged an aggressive campaign, launching a website dubbed "Streamline 66" with power point presentations, podcasts, biographies of its dissident board nominees, press releases and information on how shareholders can vote. Phillips 66 has told shareholders that its board and management team are implementing a transformative strategy that has delivered results. The company has expanded its NGL business, improved its refining cost structure and continues to position CPChem as the lowest cost producer of ethylene, Phillips 66 said. Phillips 66 told shareholders that Elliott was pushing "an aggressive short-term agenda" that would cause disruption, slow momentum and jeopardize shareholders' investment capital. Phillips 66 has made some adjustments since Elliot started to agitate for change. In addition to adding Pease to the board, the company recently agreed to sell off some of its European retail business , and expects about $1.6bn in pre-tax cash proceeds from the sale that it will use toward debt reduction and shareholder returns. But the refiner has resisted the other major Elliott recommendations to divest its midstream business and sell its 50pc share of CPChem, saying earlier this month that the Phillips board has evaluated them and "came to the conclusion that neither action is in the best interest of long-term shareholders at this time". Meanwhile, Chevron has advised Phillips 66 of its interest in acquiring the other half of CPChem "at a reasonable value for both parties", Chevron chief executive Mike Wirth said on 2 May.

Phillips 66 vote could change company's course
Phillips 66 vote could change company's course
Houston, 19 May (Argus) — Just four of Phillips 66's 14 board members are up for election at its annual meeting this week, but the outcome could shape the future direction of the US refiner and midstream operator. Activist hedge fund Elliott Investment Management has named four of its own candidates for the vote which will come to a conclusion on 21 May, part of its multi-year effort to push the company to sell assets and focus on core businesses. Elliott, which has amassed a $2.5bn stake in Phillips 66, contends that the company has consistently trailed its industry peers and needs to streamline operations, including spinning off or selling its midstream business, selling its stake in Chevron Phillips Chemical (CPChem), and possibly other assets. Phillips 66 has told shareholders that Elliot is pushing "an aggressive short-term agenda" that would cause disruption, slow momentum and jeopardize shareholders' investments. It says the Phillips 66 board and management team are implementing a "transformative strategy" that has delivered results, expanded its NGL business, improved its refining cost structure and continues to position CPChem as the lowest cost producer of ethylene. "We don't act out of fear or short-term trends," Phillips 66 chief executive office Mark Lashier said in a first quarter earnings call last month. "We act on what we believe will create the most long-term value for our shareholders each and every time." Turning up the heat Elliott alleges that Phillips 66 suffers from "continuous poor corporate governance" and "disingenuous shareholder engagement." Elliott said its proposals could push Phillips 66 stock to more than $200 per share. The stock was trading near $124 per share Monday morning. Elliott's campaign has grown more aggressive in the months leading up to this week's shareholder meeting. It includes launching a website dubbed "Streamline 66" with slide shows, podcasts, biographies of its dissident board nominees, press releases and information on how shareholders can vote by mail, phone or online. Elliott nominees include Brian Coffman, former chief executive at Motiva; Sigmund Cornelius, former chief financial officer of ConocoPhillips; Michael Heim, former chief operating officer of Targa Resources; and Stacy Nieuwoudt, former energy analyst at Citadel. Three top shareholder advisory firms are backing the Elliott nominees in the proxy fight. Institutional Shareholder Services (ISS) and Egan-Jones are recommending all four of Elliot's dissident nominees, while Glass Lewis is backing three of the four — and supporting Phillips 66 nominee Nigel Hearne, a 35-year veteran of Chevron, because his experience "is more critical at this juncture". Phillips 66 pushback Phillips 66 has made some adjustments since Elliot started to agitate for change. In February 2024 it appointed former Motiva and Cenovus downstream executive Robert Pease to the board to address Elliott's concerns about a shift in focus from refining to midstream. And this year it agreed to sell off some of its European retail business , and expects about $1.6bn in pre-tax cash proceeds from the sale that it will use toward debt reduction and shareholder returns. But for the other Elliott recommendations to divest from midstream and sell its 50pc share of CPChem, Phillips 66 said the board has evaluated them and "came to the conclusion that neither action is in the best interest of long-term shareholders at this time". In additon to Hearne, Phillips 66's slate for the open board seats includes putting up Pease and current director John Lowe for re-election and nominating Howard Ungerleider, a former Dow president and chief financial officer. Current board members Gary Adams and Denise Ramos will not stand for re-election. Analysts with US bank TD Cowen said they "suspect Elliott could get some or all of its board members elected" and there could be larger board turnover next year if shareholders approve an Elliott proposal to require each director to submit a resignation to the board every year. The most likely outcome of an Elliott win is that the board "more deeply examines a midstream restructuring", TD Cowen said.
