Long Son Petrochemical Restarts Vietnam Operations after 10-Month Suspension

---

Researched by Industrial Info Resources (Sugar Land, Texas)--Long Son Petrochemical Co., Ltd (LSP), a subsidiary of Thailand's Siam Cement Group (SCG), invested more than $5 billion to build a petrochemical complex in Long Son Commune, Ho Chi Minh City (formerly Vung Tau City before the province was merged), Vietnam. The project includes an olefins plant with a 1.35 million ton-per-year (T/Yr) capacity and three polyolefin plants that can produce a combined 1.4 million T/Yr, along with essential port and storage facilities. In October 2024, just a month after the start of commercial operations, the plant was shut down due to volatile crude oil prices, which causes profits to fall.

In the third quarter of this year, oil prices showed a downward trend. This turn of events resulted in LSP resuming operations on August 20 after a 10-month suspension.

Alongside the restart, LSP is implementing the Long Sơn Petrochemical Enhancement Project (LSPE) to build two ethane storage tanks with an investment of US$500 million. Each tank will have a capacity of approximately 55,000 tons and require a temperature as low as -90 degrees Celsius. The construction is expected to be completed by the end of 2027 .
