Another offshoot of deflation that is particularly worrying, she said, has manifested itself in a series of major accidents that have hit the plants of Japan s industrial giants in recent years. The examples cited by Hama included a fire that destroyed a tire factory of Bridgestone Corp. in Kuroiso, Tochigi Prefecture and a fire and explosion at Nippon Steel Corp. s Nagoya ironworks, both of which happened last September. 

Commercial plants The first commercial plant incorporating CT-BISA with a 70,000-tpy capacity was constructed for Shin Nippon Bisphenol Co., Japan, and has been successfully operated since 1991, in collaboration with Nippon Steel Chemical Co., Ltd. This plant has been revamped by Chiyoda to 95,000 tpy in 1999. A second facility, with 25,000-tpy capacity for Taiwan Prosperity Chemical Corp., Taiwan, has been successfully operated since 1995. A third facility, with 70,000-tpy capacity for Mitsubishi Chemical Corp., Japan, started up in 1998 and has been revamped to 100,000 tpy by Chiyoda in 2000. In 2000, two new contracts have been awarded to CT-BISA Process, i.e., a 100,000-tpy BPA plant by Mitsubishi Chemical Corp., Japan and a 25,000-tpy plant by Bluestar, China-... 

In this sector, the Stretford Process offered by British Gas Corp. and the Takahax Process of Tokyo Gas Cie. Ltd. have prevailed over the older processes of this type such as Giammarco-Vetrocoke, Ferrox, Thylox and others [2.4]. A certain preference for the former can be observed in the USA and Europe, whereas the latter is more frequently used in Japan. The Takahax process, which exists in 4 versions in combination with the Hirohax process developed by Nippon Steel, is specifically tailored to coke oven gas cleaning and may therefore be left unconsidered here.
