Clariant announced the successful startup of its Catofin catalyst at Hengli Group’s new mixed-feed dehydrogenation plant in Dalian, China. The new unit combines propane dehydrogenation (PDH) with iso-butane dehydrogenation (BDH) process technologies, and it will produce over one million tons of olefins per year — becoming the world’s largest plant using Catofin catalyst technology.

Dalian/China; Munich/Germany — Founded in 1994, Hengli Group is one of China’s foremost suppliers of petrochemicals. Hengli Group’s new dehydrogenation plant in Dalian, China is designed to process 500 KTA of propane and 800 KTA of iso-butane feeds to produce propylene and iso-butylene. For its dehydrogenation plant, the project uses Clariant's Catofin catalyst technology.

The state-of-the-art process pairs the Catofin technology with Mc Dermott’s Lummus process technology and is said to enable high reliability and yields, cost efficiency and simplicity. In addition to the catalyst, the facility is using the Germany provider’s Heat Generating Material (HGM) to produce its on-purpose olefins.
