Technip Energies has secured a contract from Long Son Petrochemicals for the Long Son Petrochemicals Enhancement (LSPE) project located on Long Son Island in Vietnam.
The contract covers engineering and procurement services, site assistance, and the supply of proprietary burner technologies for the facility’s cracking furnaces. The project will upgrade the existing steam cracker by shifting from naphtha to ethane feedstock using Technip Energies’ proprietary ethylene technologies.
The upgrade is designed to improve feedstock flexibility, enhance energy efficiency, and increase ethylene recovery rates. By incorporating ethane into the feedstock mix, the project aims to reduce production costs, lower carbon intensity, and strengthen operational resilience amid global market volatility.
This development is notable as it represents one of the few recent global projects converting a naphtha-based steam cracker to ethane, reflecting a broader industry shift toward more efficient and lower-carbon petrochemical processes.
The project builds on the longstanding partnership between Technip Energies and Long Son Petrochemicals, following the company’s earlier delivery of engineering, procurement, and construction services for the complex’s cracker unit between 2018 and 2023. The contract, recorded in the first quarter of 2026, further strengthens Technip Energies’ position in global petrochemical and energy transition projects.
