Clariant, CB&I to design new propane dehydrogenation unit in China

Comments Email

Clariant has been awarded a contract by China’s Dongguan Grand Resource Science & Technology Co. Ltd. to develop a new propane dehydrogenation unit in cooperation with CB&I.

The project includes the licence and engineering design of the single-train dehydrogenation unit, which is to be built in the southern Chinese city of Dongguan, Guangdong.

Clariant's technology partner CB&I will base the plant's design on its Catofin catalytic dehydrogenation technology, which uses Clariant's tailor-made Catofin catalyst and heat generating material (HGM).

The Catofin dehydrogenation process produces isobutylene, propylene or amylenes from isobutene, propane or isopentanes respectively.

The process, according to the Swiss speciality chemicals company, operates at “optimum reactor pressure and temperature”, in order to improve the conversion of propane and generate a high yield of propylene.

HGM is a metal-oxide material which is designed to increase the selectivity and yield of Catofin units.

"We are proud to be part of this important project for Dongguan Grand Resource in China. As proven in previous cases, the Catofin catalyst and the HGM technology will not only bring our new client significant commercial advantages, but will also help them to reduce emissions," said Stefan Heuser, senior vice president and general manager business unit catalysts at Clariant.
