Technip Energies passes all performance tests for SP Olefins’ gas-cracking ethylene plant

Technip Energies provided the technology licensing and process design to SP Olefins (Taixing) Co. Ltd., for China’s first gas-cracking ethylene plant in Taixing, Jiangsu Province, China.

The 780,000 tpy plant successfully started up in August 2019, reaching on-spec olefins shortly thereafter. Earlier this year, the plant passed all performance guarantees, and the final acceptance certificate was recently issued, which was delayed due to COVID-19. The Taixing plant is not only the first gas-cracking ethylene plant in China, but also the first plant to use imported U.S. ethane as feedstock.

In addition to the ethylene cracker technology, Technip Energies provided key proprietary technology designs including Ripple Trays. Technip Energies’ Ultra Selective Conversion (USC) W-coil ethylene furnace technology combines high energy efficiency and high yields, resulting in CO2 emissions reduction. It ranks in the first quartile of comparable crackers for lowest CO2 production per ton of high value chemical production.

Bhaskar Patel, Senior Vice President of Technip Energies Process Technology, commented: “We are very pleased with passing the final acceptance test and performance guarantees of the SP Olefins plant. As the first ethylene cracker of its kind in China, this is a great milestone and an example of how our technologies improve energy efficiency and reduce CO2 emissions.”
