BAYER MATERIALSCIENCE
Successful test for gas phase phosgenation technology at Caojing TDI plant / 250,000 t/y facility to be commissioned successively this year
Bayer MaterialScience (BMS, Leverkusen / Germany; www.bayerbms.com) has successfully tested its gas phase phosgenation technology at its new world-scale toluene diisocyanate (TDI) plant in Caojing, Shanghai / China. The integrated facility is due to come on stream successively this year, until it reaches an annual output of 250,000 t/y. It was originally scheduled to start operations in 2010 – see Plasteurope.com of 22.10.2008.
Applied to a large facility of this kind, BMS’ gas phase phosgenation technology can reduce solvent consumption by up to 80%, while cutting energy use by about 60%. In addition, the technology also cuts operating costs, BMS says, adding that carbon dioxide emissions can be reduced by about 60,000 t/y. By adopting this technology, the Leverkusen-based group asserts, investment costs for large-scale facilities can be cut by about 20%.
