August 13, 2025 [Hydrocarbon Processing]- Vietnam’s Long Son Petrochemicals, a unit of Thailand’s SCG Chemicals, will resume its operations late this month following a suspension from November last year, SCG said.

The decision to resume operations at the $5.4-billion petrochemical complex in southern Vietnam came after a decline in crude oil prices that has improved its operational feasibility, SCG said in an emailed statement.

In November, SCG, Thailand’s largest industrial conglomerate and the owner of SCG Chemicals, shut the complex due to low margins.

“While market conditions remain challenging, the decision reflects a proactive approach to maintaining long-term operational continuity and readiness,” the company said in the Tuesday statement.

It said a $500-million project to enhance the plant’s competitiveness by adopting ethane as feedstock is progressing as planned, with completion expected in 2027.

Long Son Petrochemicals has annual capacity to produce 500,000 tons of high-density polyethylene, 500,000 tons of linear low-density polyethylene and 400,000 tons of polypropylene, using mostly naphtha and propane imported from the Middle East as raw materials.
