Baytown, Texas -- A team at Bayer MaterialScience llc's Baytown, Texas, plant has substantially reduced energy consumption for the TDI (toluene diisocyanate) unit there, by optimising site operations.
And at the 2011 Industrial Energy Technology Conference (IETC), held 17 -19 May in New Orleans, the BMS employees received the American Chemistry Council's (ACC) Responsible Care Energy Efficiency Exceptional Merit award for its efforts.
The TDI team worked with BMS's Isocyanates Technology Centre in Leverkusen, Germany to generate ideas for improvements. Energy-saving projects reduced overall steam use, exploited lower-value steam, and provided ways to recover waste steam.
"By making these changes to the TDI process, we were able to reduce steam usage by approximately 20 percent over two years," said Don Pferdehirt, TDI production lead at the Baytown TDI unit, in a company statement. "Using less steam not only lowers operating costs, but also is equivalent to reducing carbon dioxide (CO2) emissions by approximately 45 000 tons per year."
