Mitsui Chemicals Inc. unit employs OCT technology licensed by ABB Lummus Global
BLOOMFIELD, NJ, November 10
-- ABB announced today that Mitsui Chemicals, Inc. has commissioned an olefins conversion unit at its Osaka Works in western Japan. The new unit employs the Olefins Conversion Technology (OCT), licensed by ABB Lummus Global, to convert ethylene and butenes to propylene. Propylene capacity at the site has increased by 50 percent, from 280,000 tons to 420,000 tones per year (TPA). The unit started up flawlessly with on-specification product three hours from oil-in, and with performance tests successfully competed in a little over one week. This new unit is the first plant installation in Japan to produce propylene using the OCT technology.
This project is part of Mitsui’s strategic restructuring to meet increasing propylene demand in Asia on a competitive basis. By this revamp, the propylene-to-ethylene production ratio can be raised from 0.6 to greater than 1.0 to meet the olefins demand variation.
The technology is based upon the principle of metathesis to catalytically produce propylene via reaction of C4s and ethylene. This process has operated successfully in the U.S. for many years and eight other units are in various stages of design and construction worldwide. A second plant in the U.S. will begin operation shortly.
Propylene is the raw material for automobile bumpers, films, electronic circuits, DVDs and various derivatives of phenol and acrylonitrile.
