Major Project Technip Energies awarded contract for Long Son Petrochemicals enhancement project in Vietnam

Long Son Petrochemicals have awarded a contract to Technip Energies for its Long Son Petrochemical Enhancemeant Project located in Lon Son Island, Vietnam. The project is among the first worldwide in recent years to convert a naphtha-based steam cracker to ethane.

Nanterre/France – Technip Energies has been awarded a contract by Long Son Petrochemicals (LSP) for its Long Son Petrochemicals Enhancement (LSPE) project, located on Long Son Island, Vietnam.The contract covers engineering and procurement services, site assistance, 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 using Technip Energies’ proprietary ethylene technologies, including its Ultra Selective Conversion (USC) furnace design and Heat-Integrated Rectifier System (HRS), delivering high selectivity, enhanced energy efficiency and optimized ethylene recovery.

This strategic initiative will incorporate large quantities of ethane into the existing naphtha and propane feedstock mix, aiming to optimize feedstock efficiency, achieve substantial cost reduction, significantly reduce carbon footprint intensity, and strengthen long-term strategic resilience amidst global market volatility. This project is among the first worldwide in recent years to convert a naphtha-based steam cracker to ethane, as forward-looking petrochemical producers prioritize feedstock diversification and the adoption of lower-carbon inputs to ensure supply chain security.

As steam crackers are at the heart of petrochemical complexes, improvements in feedstock flexibility can have a significant impact on the overall value chain. They transform hydrocarbon feedstocks such as naphtha, liquefied petroleum gas (LPG), or ethane into essential building blocks like ethylene and propylene. These molecules are used to manufacture everyday products including plastics, packaging materials, textiles and components for consumer goods.

This new project builds on the long-standing collaboration between Technip Energies and Long Son Petrochemicals. Technip Energies previously delivered the engineering, procurement and construction (EPC) of the complex’s cracker unit between 2018 and 2023.

Stéphane Mespoulhès, SVP Ethylene, Polyolefins & Fertilizers Product Line at Technip Energies, commented: "We are pleased to be entrusted again by Long Son Petrochemicals in the development of this strategic complex. This renewed trust builds on the successful delivery of the original cracker, and this new project demonstrates how our ethylene technologies and execution capabilities can help clients adapt their facilities to evolving market dynamics while enhancing flexibility and competitiveness."

This award was recorded in Q1 2026 in the Technology, Products & Services segment.
