Clariant selected for new propane dehydrogenation unit in China
MUNICH — Clariant, a company in specialty chemicals, announced an agreement with Xuzhou HaiDing Chemical Technology Co. Ltd. to develop a custom-built CATOFIN catalyst and propane dehydrogenation (PDH) unit in cooperation with its technology partner CB&I. The project includes the license and engineering design of the unit, which is to be built in Pizhou, Jiangsu Province, China.
The Xuzhou HaiDing plant is designed to produce 600 KTA of propylene and will be based on Clariant’s CATOFIN catalytic dehydrogenation technology, which employs the company’s CATOFIN catalyst and Heat Generating Material (HGM).
CATOFIN is a dehydrogenation catalyst used for the production of olefins, such as propylene or isobutylene, from light paraffin feedstocks. HGM is a patented metal-oxide material loaded with the catalyst that increases the selectivity and yield of CATOFIN units. To maximize the yield of propane to propylene, the process operates at thermodynamically advantaged reactor pressure and temperature and utilizes a highly selective catalyst.
Globally, nine CATOFIN propane dehydrogenation units have been successfully commissioned and continue to reliably produce more than 4,500 KTA of propylene.
