Technip Energies has won a contract from Long Son Petrochemicals to convert its Vietnam steam cracker from naphtha to ethane feedstock. The project includes engineering, procurement, site assistance, and proprietary burner supply, targeting lower carbon intensity and feedstock cost reduction.
According to a company announcement, Technip Energies has been awarded a contract by Long Son Petrochemicals Co., Ltd. (LSP) for the Long Son Petrochemicals Enhancement (LSPE) project on Long Son Island, Vietnam.
The scope covers engineering, procurement services, site assistance, and supply of proprietary burners for cracking furnaces.
The project will convert the existing steam cracker using Technip Energies’ Ultra Selective Conversion (USC®) furnace design and Heat-Integrated Rectifier System (HRS®) to process ethane alongside naphtha and propane. This conversion is among the first globally in recent years to shift a naphtha-based cracker to ethane.
This development matters because steam crackers are central to plastics, packaging, and textile value chains. Feedstock diversification to ethane improves cost efficiency and reduces import dependence on naphtha.
For petrochemical operators and investors, the project signals growing momentum toward lower-carbon feedstocks and supply chain resilience amid volatile global hydrocarbon markets. Technip Energies previously delivered EPC for the cracker unit between 2018 and 2023, underscoring an ongoing operational relationship.
Technip Energies is a Paris-based engineering and technology firm specializing in energy transition and petrochemicals.
Long Son Petrochemicals operates Vietnam’s largest integrated petrochemical complex.
