Clari­ant sup­plies cat­a­lysts for world’s largest propane de­hy­dro­gena­tion unit

Chemical Industry Digest - - News & Views -

Clari­ant has been awarded a con­tract by Jin­neng Sci­ence & Tech­nol­ogy Com­pany, to de­sign the world’s largest sin­gle-train propane de­hy­dro­gena­tion unit in col­lab­o­ra­tion with CB&I.

The plant will be lo­cated in Qing­dao, Shan­dong Prov­ince, China and have the ca­pac­ity to pro­duce 900,000 met­ric tons per an­num (MTA) of propy­lene when com­pleted. The project is based on CB&I’s Catofin propane de­hy­dro­gena­tion tech­nol­ogy com­bined with Clari­ant’s cus­tom-made Catofin cat­a­lyst and Heat Gen­er­at­ing Ma­te­rial. The part­ners have pre­vi­ously col­lab­o­rated on nu­mer­ous projects to de­sign spe­cial­ized propane de­hy­dro­gena­tion units both in China and around the world.

The Catofin process is used to pro­duce olefins, such as propy­lene or isobuty­lene, from light paraf­fin feed­stocks. Fea­tures men­tioned by the com­pany in­clude a high op­er­a­tional re­li­a­bil­ity, ef­fi­ciency, and max­i­mum con­ver­sion of raw ma­te­ri­als at op­ti­mum re­ac­tor pres­sure and tem­per­a­ture. In­cor­po­rated into the process, Clari­ant’s patented metal-ox­ide Heat Gen­er­at­ing Ma­te­rial in­creases the cat­a­lyst’s se­lec­tiv­ity and yield, while con­serv­ing en­ergy and re­duc­ing emis­sions.
