Summary:Applicability of the chemical absorption process to carbon dioxide removal and recovery under effluent gas conditions equivalent to those for coal-fired power plants was tested. From the pilot plant test results using KS-3 absorbent at an exhaust gas flow rate of 450m3/h, overall performance of the system was confirmed by about 200 hours' operation with 50ppm coexisting SOx. Furthermore it is found, that longer operation is permitted, judging from the experimental evidence of KS-3's corrosion properties under coal-fired conditions compared to those at LNG-fired power plants.
