Vietnam's sole cracker operator Long Son Petrochemical (LSP) has extended the shutdown of its cracker and associated downstream units in Ba Ria-Vung Tau to June, to address technical issues.

LSP shut its cracker and downstream units on 21 February because of equipment issues. Siam Cement (SCG), the parent company of LSP, subsequently issued a force majeure on products the following day.

SCG was initially expecting the cracker to restart in about 2-4 weeks after the shutdown in February. But the firm filed a statement to the Stock Exchange of Thailand (SET) on 22 March, stating that the technical difficulty is still under investigation and the LSP complex is expected to restart in June.

LSP's cracker is a mixed feed cracker with a nameplate capacity of 950,000 t/yr for ethylene, 400,000 t/yr for propylene and a 100,000 t/yr butadiene extraction unit. Downstream units are polymer-focused, with a 500,000 t/yr high-density polyethylene (HDPE) plant, a 500,000 t/yr linear low-density polyethylene (LLDPE) unit and a 400,000 t/yr polypropylene (PP) unit.

SCG offered spot HDPE, LLDPE and PP supplies from its new LSP complex to the market earlier this year but has ceased offers since late February, after the force majeure announcement. SCG also stated in its statement filed to the SET that its Rayong Olefins (ROC) cracker in Map Ta Phut, Thailand has resumed operations. The producer is expected to ramp up production at its 920,000 t/yr HDPE unit and 720,000 t/yr PP unit in Thailand following the restart of the ROC cracker, and will resume supply of these grades to the market.

The ROC cracker was restarted late last week and has achieved on-specification olefins products since then, according to sources close to the company. The cracker was shut for maintenance since mid-November 2023.

The ROC cracker has a nameplate capacity of 800,000 t/yr of ethylene and 400,000 t/yr propylene. SCG also owns another cracker at the same site — the Map Ta Phut Olefins cracker with capacity of 1mn t/yr of ethylene and 500,000 t/yr of propylene. Both the crackers are currently operating at near-full run rates.

Phillips 66 weighs Louisiana refinery expansion

Houston, 20 March (Argus) — US independent refiner Phillips 66 is seeking state tax incentives for a possible expansion of its 264,000 b/d refinery in Lake Charles, Louisiana. The expansion would increase production capacity and improve operational efficiency through upgrades and new specialized equipment, according to a summary of the project posted by the Louisiana Department of Economic Development. The agency, which administers state incentives, said that the Phillips 66 project is in review. Phillips 66 said today that it does not typically comment on refinery operations, regulatory filings or commercial activities. According to the Louisiana Department of Economic Development posting, the $99mn upgrade would include adding a 5MW steam turbine power generator, a boiler feedwater chemical system, LCR kerosene product rundown system upgrades, a reactor, a naptha fractionator, and other pieces of equipment. The budget includes $40mn for machinery and $59mn for labor and engineering. The project is estimated to be completed at the end of 2027.

Upper Mississippi River reopens for transit

Houston, 20 March (Argus) — The first towboat arrived at St Paul, Minnesota, today, marking the start of the 2025 navigation season on the upper Mississippi River, according to the US Army Corps of Engineers (Corps). The Neil N. Diehl passed through Lock 2 at Hastings, Minnesota, with nine barges, crossing into St Paul on 19 March. Tows reaching St Paul signify the unofficial start of the navigation season, as St Paul is the last port to open on the Mississippi River after winter ice thaws each year. This is considered an average start time for the navigation season, which typically opens the third week of March. The first tow to reach St Paul in 2024 arrived on 17 March. The Corps released the final Lake Pepin ice measurements of 17in on 12 March and was unable to take new measurements this week since the ice had melted significantly. Lake Pepin measurements help determine when the ice will be thin enough for barges to transit up river.

Brazil central bank raises target rate to 14.25pc

Sao Paulo, 20 March (Argus) — Brazil's central bank raised its target interest rate by 1 percentage point to 14.25pc amid accelerating inflation in a decelerating — but still heated — economy. The hike in the target rate, announced Wednesday, was the fifth in a row from a cyclical low of 10.5pc at the end of September last year, partly prompted by accelerating depreciation of the currency, the real, to the US dollar. Brazil's annualized inflation hit 5.06pc in February and is poised to keep accelerating. The bank's Focus economic report increased its inflation forecast to 5.7pc for the end-of-year 2025 from 5.5pc in January, when the bank's policy-making committee last met. Brazil's current government has an inflation ceiling goal of 3pc with tolerance of 1.5 percentage point above or below. The bank has recently changed the way it tracks the inflation goal. Instead of tracking inflation on a calendar year basis, it now monitors the goal on a rolling 12-month basis. The bank cited heated economic activity and a strong labor market as factors that have contributed to rising inflation. But the bank forecasts "modest GDP growth" for Brazil of almost 2pc in 2025, down from 3.4pc growth last year. Further tightening will also be linked to global economic uncertainty prompted by US president Donald Trump's aggressive trade and other policies and the monetary policies of the US Federal Reserve , according to the bank. Brazil's target interest rate is expected to keep rising at the bank's next meeting in 6-7 May, albeit to "a lesser extent" as the contributing factors are set to moderate, according to the committee.

Commission to engage on future of EU chemicals industry

Commission to engage on future of EU chemicals industry

London, 20 March (Argus) — The European Commission said it will actively engage in strategic dialogue with the European chemicals industry to help it manage high energy prices and the costs of modernisation and transition. Calls for action and support have grown as more plant closures are announced and many businesses and assets are considered at risk. "I believe we will be able to develop a plan. It will take the necessary form, though I have no announcements to make at this stage," Stephane Sejourne, the EU commissioner responsible for prosperity and industrial strategy, told Argus. "We are starting at the level of the commissioners. That being said, the industry will, of course, be present, and we intend to develop sectoral plans with all stakeholders. We will need to examine with stakeholders how we can modernise this sector and invest in it, given the shrinking margins caused by international competition and the high energy prices in Europe," he said. Sejourne said the plan is to "define the key challenges and the possible shape of the relevant legislative texts, while maintaining the same approach as with other sectors". Business plans will be the priority of the discussions, rather than new sectoral regulations, he said, adding that the aim is to enhance the competitiveness of the sector. "Simplification, harmonisation, modernisation and financing will take precedence over regulation," he said. Sejourne said he has discussed with EU ministers "the urgent need to modernise steam crackers, which are over 40 years old in Europe". These units are "environmentally inefficient, underperforming and do not enhance the sector's competitiveness", he said. The chemicals industry will be "crucial" for other industries, Sejourne said. "As part of the reindustrialisation efforts that have been launched and the announcements made by the commission, we will need the chemical industry." Critical Chemicals Act Sejourne's comments came after eight European countries called for measures to support the production of key chemicals in the EU as the bloc faces pressure from rising costs and competition. The proposed "EU Critical Chemicals Act" would support the development and decarbonisation of existing chemical plants while fostering alternative carbon sources, the eight countries said. Signatory countries — the Czech Republic, Hungary, Italy, the Netherlands, Romania, Slovakia, Spain and France — highlighted 18 molecules as key to European strategic value chains, five of which they labelled as critical. The list includes ethylene, propylene, butadiene, benzene, toluene, xylene, phenol, styrene, ammonia, methanol, chlorine, sodium hydroxide, sulphur, silicon, sodium carbonates, hydrofluoric acid, methionine and lysine. Those singled out as critical were ethylene, butadiene, benzene, ammonia and sodium carbonates. The signatories welcomed the EU's recent "Clean Industrial Deal", a plan to turn decarbonisation into a driver of EU growth, but argued that the chemical industry needs support to successfully decarbonise. Full decarbonisation of a single steam cracker can cost more than €1bn, highlighting the scale of investment required, the eight countries said. The European Council adopted the Critical Raw Materials Act in March 2024, which aims to protect supply chains for rare metals. Similar measures are needed for the chemical industry because they are essential to core industries including defence, health and construction, argued the signatories. Plant closures have accelerated in Europe. Last year, ExxonMobil closed its Gravenchon cracker in France and Sabic closed one of its two crackers in Geleen in the Netherlands. Eni's Versalis subsidiary will close its two remaining crackers in Italy this year. And US firm Dow has idled one of its three crackers in Terneuzen in the Netherlands. At least three other crackers in the region have been put for sale by their owners. Besides steam crackers, many more chemical and downstream derivatives units have either been closed, are operating at low rates or are up for strategic review or sale.

US ethane cracking margins at 10-month low

US ethane cracking margins at 10-month low

Houston, 20 March (Argus) — US ethane cracking margins have fallen to the lowest in 10 months on rising ethane cash costs and falling spot ethylene prices at Mont Belvieu, Texas, according to an Argus generic model. Ethane cracking margins on Wednesday fell to 10.5¢/lb, the lowest level since May 2024. Margins have steadily narrowed from a peak of 24.75¢/lb two months ago, when a freeze took several US Gulf coast crackers off line and spiked ethylene prices to 35.25¢/lb in a trade at the Enterprise Products Partners (EPC) system at Mont Belvieu. The decline in cash margins largely follows falling domestic ethylene spot prices as US crackers have incrementally restarted and ramped up production since mid-January. US spot EPC ethylene traded Wednesday at 24.75¢/lb, the first trade below 25¢/lb since late November. The more than 10¢/lb decline in ethylene spot prices does not fully account for eroding ethane cracking margins. Ethane costs have risen by more than a third through February and into March, hitting an 18-month high last week of 31.1875¢/USG. Higher ethane costs have largely followed higher natural gas prices at the benchmark Henry Hub, which hit a two-year high at $4.491/mmBtu on 10 March stemming from tightening US gas inventories. Natural gas prices serve as a price floor for ethane because it is separated from raw natural gas during processing. The 60pc drop in ethane cracking margins over the past two months is unlikely to affect ethane-based ethylene production, as margins of at least 4-5¢/lb are generally still profitable for cracker operators. US ethane cracking margins in 2024 averaged 14-15¢/lb, according to Argus data. Ethane structurally remains the most advantaged feedstock on the US Gulf coast and was last surpassed briefly by a competing feedstock more than 18 months ago. Propane cracking margins are currently negative and the butane cracking margin has ranged from 3.5-8¢/lb this month.
