Chementator: A propane-based AN process makes its commercial debut  

By Gerald Ondrey |

This summer, Asahi Kasei Chemicals Corp. (AKCC; Tokyo, Japan; edlinks.chemengonline.com/7373-532) plans to begin construction on a plant for producing 200,000 m.t./yr of acrylonitrile (AN) and a plant for making 70,000 m.t./yr of methyl methacrylate (MMA), at Map Ta Phut, Rayong, Thailand. The $80-million investment — a joint venture with PTT Public Company Ltd. (Bangkok, Thailand) and Marubeni Corp. (Tokyo) — is scheduled to startup in late 2010. The AN plant will be the first grassroots facility in the world to make acrylonitrile from propane, instead of propylene, using AKCC’s new process ( CE, September 2006, p. 18). With a stable, competitive supply of propane secured by PTT, the new AN plant is expected to deliver "exceptional" cost competiveness in the global AN market, says AKCC. In addition, byproduct hydrogen cyanide from the AN plant will be used as feedstock for the MMA facility, which will use a new acetone-cyanohydrin process to make MMA. This integration of the AN and MMA facilities will achieve "superior cost competiveness," says AKCC.   Click here for a full pdf version of the Chementator Section
