Hydrocarbon Engineering,

Technip Energies provided the proprietary technology and process design for Hengli Petrochemical (Dalian) Chemical Co. Ltd.’s (Hengli) mega 1500 tpy liquid ethylene plant in Dalian, Liaoning Province, China. The plant successfully started up at the beginning of 2020 to reach its capacity shortly after the start-up, and despite COVID-19 context, passed all performance guarantees and the final acceptance test in the fourth quarter. Known as the largest liquids ethylene cracker in China, the plant was completed and started up in 13 months since commencement of the construction, as part of a 20 000 tpy refinery complex which broke ground in 2017.

In addition to the ethylene cracker technology, Technip Energies provided key proprietary technology components, including a heat integrated rectifier system, ripple trays and wet air oxidation process. Technip Energies’ ultra selective conversion (USC®) U-coil and W-coil ethylene technology combines high energy efficiency and high yields, resulting in CO2 emissions reduction. It ranks in the 1st quartile of comparable crackers for lowest CO2 production per relative amount of high value chemical production.

Stan Knez, Senior Vice President of Technip Energies Process Technology, commented: “We are very pleased with passing the final performance acceptance of the Hengli cracker. This is a great milestone for the complex and another example of our know-how to improve energy efficiency and reduce CO2 emissions through our proven ethylene technology.”
