Leverkusen, Germany -- Bayer MaterialScience has successfully tested its innovative gas-phase-phosgenation technology at a new TDI (toluene diisocyanate) plant being commissioned at Caojing in Shanghai, China.
The process technology reduces solvent consumption by around 80 percent in a large production facility, cutting energy consumption by up to 60 percent, BMS said in a 26 July announcement.
The company said the use of this technology enables a significant reduction in operating costs. Compared with conventional production facilities of similar size, carbon dioxide emissions can be cut by around 60 kilotonnes a year, according to BMS, and the technology also cuts investment costs by about 20 percent.
"The use of our gas phase phosgenation technology for the first time in a manufacturing plant of this size clearly indicates that Bayer MaterialScience is at the forefront of modern and environmentally advanced technologies," said Patrick Thomas, ceo of Bayer MaterialScience.
The world-scale TDI facility at BMS's integrated production site at Caojing is expected to come on stream stepwise later this year, building next year to its full capacity of 250 kilotonnes of TDI per year. The company's global TDI capacity will increase to over 700 kilotonnes a year.
