Technip Energies provided licensing, engineering, procurement, construction, commissioning, start-up and initial operation for the 1350 KTA(1) cracker.

As Vietnam’s first olefins plant, the flexible feed cracker, can utilize both naphtha and liquified petroleum gas feeds to produce ethylene, propylene, and butadiene (2).

The plant successfully started up end 2023 to reach its full capacity shortly after the start-up and pass its first performance test in February 2024. The plant, which broke ground end 2018, includes Technip Energies’ licensed ethylene technology, including Ultra Selective Conversion (USC®) furnaces preferred for high selectivity and low cost, and the Heat-Integrated Rectifier System®, preferred for energy efficient ethylene recovery. 

Bhaskar Patel, Senior Vice President, Sustainable Fuels, Chemicals & Circularity, commented: “We are pleased with passing the final performance acceptance of the Long Son Petrochemicals’ olefins plant. This is a great milestone for Vietnam and another example of our know-how to improve energy efficiency through our proven ethylene technology.”
