Asahi Kasei Begins Commercial Production of World's First Propane Process for Acrylonitrile

Asahi Kasei Chemicals Corp. (AKC) has begun commercial operation of the world’s first propane process for acrylonitrile (AN) production, with the start-up and validation of a propane-process line at the Ulsan Plant of its Korean subsidiary Tongsuh Petrochemical Corp. An existing 70,000 ton/year AN line was modified to use the propane process.

As a key element of its Growth Action – 2010 mid-range corporate initiative, the Asahi Kasei Group has marked its AN business for strategic global expansion, especially in rapidly growing Asian markets. In an environment of continuously high prices for petroleum and its derivatives, the propane process for AN is a significant breakthrough in that it enables the use of gas-derived feed, thereby reducing dependence on feedstocks whose prices are linked to the oil price. Commercial validation of the propane process will serve to strengthen the operational base, providing a new option for competitive AN production, and is an important milestone in the advancement of a plan by AKC to build a large-scale propane-process AN plant in Thailand, in a joint venture with PTT Plc.
