- Long Son Petrochemicals awarded Technip Energies the LSPE contract to convert its Long Son Island steam cracker from naphtha to ethane.
- Scope covers engineering and procurement services, site assistance and supply of proprietary burners for the cracker furnaces.
- The conversion will use Technip Energies' Ultra Selective Conversion (USC) furnace design and Heat-Integrated Rectifier System (HRS) to improve ethylene selectivity, energy efficiency and recovery.
- Technip Energies previously delivered the cracker EPC between 2018 and 2023.
Project overview
Technip Energies was awarded a contract by Long Son Petrochemicals for the Long Son Petrochemicals Enhancement (LSPE) project on Long Son Island, Vietnam, to convert the site’s existing steam cracker from naphtha to ethane feedstock.
Scope and technology
Contract scope includes engineering and procurement services, site assistance and supply of proprietary burners for the cracker furnaces, using Technip Energies’ ethylene technologies such as the Ultra Selective Conversion (USC®) furnace design and the Heat-Integrated Rectifier System (HRS®) to improve ethylene selectivity, energy efficiency and recovery.
Feedstock change and expected impacts
The project will add large quantities of ethane to the current naphtha and propane mix to optimize feedstock efficiency, lower operating costs, reduce carbon intensity and enhance supply-chain resilience amid market volatility; converting a naphtha-based steam cracker to ethane is among the first such projects globally in recent years.
Background and accounting
Technip Energies previously executed the EPC of the complex’s cracker unit between 2018 and 2023; this award was recorded in Q1 2026 in the Technology, Products & Services segment.
