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 includes engineering and procurement services, site support, and the supply of proprietary burners for the plant’s cracking furnaces. The project will convert the existing steam cracker from naphtha to ethane feedstock, leveraging Technip Energies’ advanced ethylene technologies such as the Ultra Selective Conversion (USC®) furnace and Heat-Integrated Rectifier System (HRS®), enabling higher selectivity, improved energy efficiency, and enhanced ethylene recovery.
This strategic upgrade will integrate significant volumes of ethane into the current naphtha and propane feedstock mix, improving operational efficiency, reducing costs, lowering carbon intensity, and strengthening long-term resilience against market fluctuations. Notably, this is among the first global projects in recent years to convert a naphtha-based steam cracker to ethane, reflecting a growing industry focus on feedstock diversification and lower-carbon solutions.
Steam crackers are central to petrochemical complexes, converting feedstocks such as naphtha, LPG, and ethane into key building blocks like ethylene and propylene—essential for producing plastics, packaging, textiles, and a wide range of consumer goods.
This project further reinforces the long-standing partnership between Technip Energies and Long Son Petrochemicals. Technip Energies previously executed the EPC of the cracker unit between 2018 and 2023.
Stéphane Mespoulhès, SVP Ethylene, Polyolefins & Fertilizers at Technip Energies, said: “We are pleased to be entrusted once again by Long Son Petrochemicals. This project builds on our successful collaboration and highlights how our technologies and execution capabilities support clients in enhancing flexibility and competitiveness in a changing market.”
