Altivia's petrochemical plant in La Porte, Texas, had a leak of hazardous phosgene gas today, prompting an alert for area residents to shelter in place.

Altivia reported an upset at the plant around 11:40am ET on 4 December that caused the release of phosgene gas. Emergency responders were dispatched to the area. The shelter in place alert was issued for residents south of Fairmont, between Bay Area and South 16th Street.

An all clear was given for the area by the early afternoon, with no traces of phosgene or other hazardous chemicals detected downwind of the Altivia facility.

Phosgene produced at the plant goes into a variety of applications from plastics additives and chemical reagents, to antibiotics and pharmaceuticals. Phosgene itself is a poisonous gas at room temperature according to the Center for Disease Control, with a variety of symptoms including coughing, burning sensation in the eyes and throat, and difficulty breathing.

Orbia pauses US PVC expansion on weak market

Orbia pauses US PVC expansion on weak market

Houston, 22 February (Argus) — Mexico-based PVC producer Orbia has suspended plans to construct a PVC plant in the US Gulf coast as weak global demand creates an over-supplied market, the company said today. The proposed plant would produce roughly 1mn t/yr. Orbia had previously delayed the timing of the expansion as the company worked to better assess market dynamics. As part of that effort, Orbia recently sent a team to China, which it sees as a major factor in its outlook for the global vinyl industry. Orbia concluded that weakness in China's real estate and construction sector, combined with the country's current supply excess, is resulting in roughly 2mn metric tonnes/yr being available for export from China. The company expects this dynamic to remain for a few years, resulting in the indefinite delay of the proposed plant. "After we complete the current phase of engineering, we will pause PVC capacity expansion investments until we see the markets supporting strong investment economics," Orbia chief executive Sameer Bharadwaj said Thursday on an earnings conference call. Orbia is moving forward with other investments, including its joint venture polyvinylidene fluoride (PVDF) plant with Syensqo, a company that was spun off from Solvay in December. Orbia said the increase in export availability from China was weakening global PVC prices at the same time as global economic slowdowns and higher interest rates are dampening demand in key markets. US PVC export prices have risen by about $80/t to $750/t fas Houston over the last month, but Orbia said prices would need to be closer to $1,000t to justify the new plant. US PVC prices have struggled to rise above $850/t since March 2023. Orbia reported revenue for its polymer solutions segment, which includes its general purpose and specialty-PVC resins as well as chlor-alkali, of $577mn, down by 15pc from the third quarter and down by 21pc from a year earlier. Revenue fell partly because of reduced sales volumes, as a result of planned maintenance and a delay with the company's ethylene joint venture plant, the company said. Lower prices for specialty PVC and caustic soda and a weaker export market also were contributing factors. US emulsion-grade (E-PVC) resin, also referred to as paste-PVC has fallen in price in recent months due to increased imports from Europe. Imported paste-PVC pricing was assessed at 65-75¢/lb cfr US east coast last week, down from a range of 65-80¢/lb in January. The company's building and infrastructure segment, which includes pipe and fittings products, reported revenues at $595mn, down by 14pc from the third quarter and down by 10pc from the same quarter of the previous year. Total company revenue fell to $1.77bn in the fourth quarter, down from $2bn in the third quarter and $2.1bn in the fourth quarter of 2022. Despite the weak performance of its chemicals business, and some of the issues present in the current market, Orbia expressed confidence that fundamentals were present for demand growth to eclipse current global supply in five years or so. Expectations for 2024 were more tempered. "We expect marginal improvement, driven by a recovery in PVC volumes, and a slight improvement in prices during the year," Bharadwaj said regarding the company's polymers solutions business. He added that these improvements would be partially offset by weaker caustic soda prices. By Aaron May Send comments and request more information at feedback@argusmedia.com Copyright © 2024.

Olin taps Lane to succeed Sutton as CEO

Houston, 20 February (Argus) — US-based chlor-alkali producer Olin has named LyondellBasell executive vice president Kenneth Lane to succeed Scott Sutton as company chief executive effective next month. Sutton will step aside on 18 March and will work with Lane for a transition period before leaving the company, Olin said on Monday. In previous discussions with investors, Sutton indicated he plans to depart Olin by the middle of the year. Sutton also stepped down from Olin's board effective 16 February, with former Dow executive William Weideman appointed to succeed him as chair. Lane has served as executive vice president of global olefins and polyolefins at LyondellBasell since 2019, including serving as interim chief executive early last year . Lane previously worked at BASF for 13 years Some Olin customers have wondered whether new leadership at the company will change how the company approaches the market, but no indications of a change in strategy have yet emerged. Olin has run plants in recent years with a focus on the weaker side of the chlor-alkali market, running operations lower and tightening supply to support price recovery for whichever product, caustic or chlorine, was performing poorly. Olin has capacity idled at two plants, St. Gabriel, Louisiana and Freeport, Texas, to try and support falling chlorine prices. The two plants combine for about 1mn t/yr of chlorine capacity. Even with the idled capacity, supply has outpaced caustic and chlorine demand, leaving US producers with longer supply levels across the chlor-alkali chain.

NE Asia EDC prices likely to remain elevated in 1H

NE Asia EDC prices likely to remain elevated in 1H

Singapore, 31 January (Argus) — Northeast Asian ethylene dichloride (EDC) spot prices are likely to sustain recent gains during the first half of 2024, with lower production rates across Asia, rising demand from PVC producers in south and southeast Asia and higher freight costs caused by shipping disruptions through the Red Sea. Argus EDC spot prices edged up by $5/t in January to $350/t cfr northeast Asia, helping chlorine netbacks into EDC to positive territory. Argus estimates chlorine netbacks into EDC have risen above zero since December, but EDC producers remain reluctant to increase operating rates as they are cautious of putting incremental caustic soda supply into a currently weak market. Standalone chlorine supply cannot be stored, forcing chlor-alkali producers to run in accordance to caustic soda buying and chlorine demand for chlor-vinyls (EDC, VCM, PVC) and other downstream derivatives. This makes chlorine supply hard to price, meaning EDC producers will reference netbacks as a means to analyse their operating plans. Rising costs for feedstock ethylene are also discouraging higher EDC operating rates in the medium-term, with Asian cracker margins negative for the past two and a half years and unlikely to recover substantially in the coming months. Argus ethylene spot prices rose by $20/t on 24 January to $900/t cfr northeast Asia, a trend likely to sustain well into the first half of the year. Lower EDC operating rates across Asia were accompanied by one major unplanned maintenance schedule at a 730,000 dmt/yr caustic soda and 840,000 t/yr EDC production facility in Al Jubail, Saudi Arabia, since the second quarter of 2023. This forced many contract buyers across Asia to seek alternative EDC spot cargoes in order to keep their PVC plants running. Caustic soda and EDC production in Saudi Arabia is likely to return to normal in mid-2024, which will keep EDC requirements across Asia elevated in the coming months as PVC producers prepare for restocking season. Indian PVC demand typically rises well ahead of the start of the monsoon season in the third quarter, and restocking demand in southeast Asia typically takes place before and after the lunar new year holidays and the Islamic holy month of Ramadan. Shipping disruptions new catalyst PVC producers across Asia have relied on US EDC imports as a means to cover any shortfalls, but these began to dwindle in recent months as US producers looked to balance caustic soda and chlorine supply against weakening buying from both sides of the electrochemical unit (ECU). Latest trade data from Global Trade Tracker (GTT) show that northeast Asia (Japan, south Korea, China, Taiwan) imported a combined 537,729t of EDC in 2023, 5pc higher than in 2022. This increase is mainly attributed to a 67pc year on year rise in US imports. But US imports have eased since 2021 as export availability was partially restricted by maintenance and a need to limit incremental chlorine and caustic soda supply. There were some EDC bookings from the US to Taiwan in January, but shipment disruptions through the Red Sea and Suez Canal are becoming of increasing concern among global chlor-vinyl producers. EDC freight rates for 10,000t cargoes from the US to northeast and southeast Asia are above $100/t, with vessel attacks in the Red Sea forcing US sellers to re-route around the Cape of Good Hope. This is profoundly higher than typical freight rates of $60-80/t via the Suez Canal, keeping US EDC import arrivals much higher priced than domestic EDC supply. Rising freight costs are likely to keep US EDC imports into northeast Asia at bay in the coming months, removing alternative feedstock EDC supply options for Asian PVC producers in the medium-term.

US rail regulator approves new emergency service rule

Washington, 24 January (Argus) — US rail regulators have adopted a rule allowing them to act faster and, on their initiative, to establish emergency rail service when carrier performance deteriorates severely. The new Surface Transportation Board (STB) rule establishes procedures for shippers to obtain relief from for service emergencies. It also allows the agency to step in even if shippers have not petitioned the agency for assistance. STB said that in recent years it had "heard informally from a broad range of stakeholders about inconsistent and unreliable rail service and issued two orders mandating service in urgent situations." Those situations included crew shortages, tight railcar supply and transportation delays. The revised emergency service rule is "a long-needed reform that will help level the playing field for shippers where rail service failures have caused an acute and serious threat to their business, or when emergency relief is necessary to protect the public," STB chairman Martin Oberman said on Wednesday. Emergency service orders are intended to help maintain rail service where there has been a substantial rail performance issue or failure that requires immediate relief. But shippers have complained to the rail agency that the process to seek assistance takes too long, which has resulted in few formal petitions "even when shippers' interests have been threatened with severe adverse consequences," STB said. The new rule, which was adopted by a unanimous STB vote, goes into effect on 23 February. STB said earlier this month it would act soon on the rule, which had been pending since April 2022 when it was introduced at the height of the recent railroad performance crisis. Action on the rule was delayed while STB focused its efforts on the service crisis, the merger of Canadian Pacific and Kansas City Southern, and other proceedings.

Bunge, Iberdrola, Enel, Drax to report on nature impact

London, 17 January (Argus) — A total of 320 organisations — including several major firms in energy, mining, chemicals and shipping — representing $4tn will start disclosing their impact on nature annually. Energy firms Iberdrola, Drax, Enel and RWE, agribusiness Bunge, mining major Vale and retailers Carrefour, Ikea and Coca Cola have agreed to start making biodiversity disclosures based on recommendations from the Taskforce on Nature-related Finance Disclosures (TNFD), which were published last September after a two-year pilot period . The recommendations are in line with the Kunming-Montreal biodiversity framework, agreed at last year's UN biodiversity summit, and are consistent with other global reporting standards such as those from the International Sustainability Standards Board. TNFD recommends firms to publicly disclose their approach to nature-related risks and impact management, as well as their metrics and targets, strategies going forward and governance oversight. A total of 106 financial institutions representing $14tn in assets under management (AUM) have also agreed to make nature-related disclosures based on the TNFD, including Bank of America, BSI, Credit Agricole, Drax, Federated Hermes, London Stock Exchange, Mitsubishi, Nippon, Nomura, Schroders and UBS. About 43pc of companies are headquartered in Europe and 42pc are in Asia-Pacific. The TNFD is related to the Taskforce on Climate-related Finance Disclosures (TCFD), which has 4,900 signatories disclosing climate impacts. The TCFD was launched in December 2015.
