MOSCOW (MRC) -- Clariant has been awarded a contract by Hengli Petrochemical (Dalian) Refinery Co. to develop an extensive propane and butane dehydrogenation unit in cooperation with CB&I, according to the companies' announcement.
The project includes the license and engineering design of the co-processing unit, which is to be built in Dalian, Liaoning Province, China.
The design will be based on CB&I’s Catofin catalytic dehydrogenation technology using Clariant’s tailor-made Catofin catalyst and Heat Generating Material (HGM) to process feedstock containing 300,000 tpy of propane and 600,000 tpy of isobutane for the joint production of propylene and isobutylene.
When completed, it will be the largest single-train co-processing dehydrogenation unit in the world, and will play a key role in Hengli’s expansion plans.
"We are very pleased to be part of this groundbreaking project for Hengli Petrochemical Refinery," said Stefan Heuser, senior vice president and general manager for Clariant's catalysts business. "The contract is further proof that our customers recognize and demand the technological and economical advantages of Catofin and HGM."
The Catofin process is recognized as a highly reliable and efficient technology for producing propylene from propane, and isobutylene from isobutane. The process operates at optimum reactor pressure and temperature to maximize conversion of propane and isobutene for a high yield of propylene and isobutylene, and correspondingly low investment and operating costs.
As MRC informed before, in 2014 CB&I and Clariant, a world leader in specialty chemicals, announced that their new Ziegler-Natta (ZN) polypropylene catalyst plant in Louisville, Kentucky, is on schedule to begin production in 2015.
Clariant AG is a Swiss chemical company and a world leader in the production of specialty chemicals for the textile, printing, mining and metallurgical industries. It is engaged in processing crude oil products in pigments, plastics and paints.
