China Tianchen Engineering Corporation (TCC) and Petrovietnam Technical Service Corporation (PTSC) have secured an engineering, procurement, and construction (EPC) contract to develop key infrastructure as part of the $500 million expansion of the Long Son Petrochemicals (LSP) complex, a project spearheaded by Thailand’s Siam Cement Group (SCG).
According to a statement from SCG on Thursday, the TCC-PTSC consortium will construct two full-containment cryogenic ethane storage tanks at the Long Son Petrochemicals facility in Vietnam’s southern coastal province of Ba Ria-Vung Tau. Each tank will have a storage capacity of approximately 55,000 tons and will operate at temperatures as low as -90 degrees Celsius. The project is slated for completion by the end of 2027.
SCG Chemicals (SCGC), a subsidiary of SCG, commenced land preparation for the $5.2 billion Long Son Petrochemicals complex in 2018, with utilities coming online in 2022 and a full test run of the complex completed in December 2023. Commercial operations (COD) began in September 2024, producing an initial output of 74,000 tons during the trial phase. At full capacity, the facility will manufacture 1.4 million tons of polyethylene and polypropylene annually.
In October 2024, SCG announced an additional $700 million investment in Long Son Petrochemicals to diversify feedstock sources by incorporating ethane imported from the United States. This move aims to enhance the complex’s long-term competitiveness by reducing feedstock costs, increasing flexibility, and lowering carbon emissions, further reinforcing SCG’s commitment to sustainable industrial growth.
