What catalyst and technology are being supplied by Clariant and Lummus for ZPC's new PDH unit in China, and what is the unit’s significance?

Clariant is supplying its CATOFIN catalyst and heat generating material (HGM) for Zhejiang Petroleum & Chemical Co.'s (ZPC) new propane dehydrogenation (PDH) unit in Zhejiang Province, China; the unit has a nameplate capacity of 1.2 million metric tons per year and is described as the world's largest licensed PDH unit. The technology involves a close collaboration where Lummus Technology provides the process expertise and exclusively licenses the CATOFIN process, while Clariant solely produces and supplies the catalysts. This marks ZPC’s first use of Lummus’ PDH technology, having previously employed an alternative PDH process.

How does the new PDH unit integrate with ZPC’s broader operations, and what role does upstream expansion play?

The propylene produced at the new PDH unit will feed into the production of petrochemical derivatives, and its operation is supported by additional propane feedstock made available through ZPC’s ongoing upstream refinery expansions. Lummus also noted that ZPC and its affiliates have long relied on Lummus technologies across their operations—including CDAlky®, ISOCRACKING, DPC, and butadiene extraction—highlighting the strategic integration of the new PDH unit within ZPC’s existing and expanding infrastructure.
