When the ,acid, gases are absorbed into the scrubbing solution, they react with alkaline compounds to produce neutral salts. The rate of ,absorption, of the ,acid, gases is dependent upon the solubility of the ,acid, gases in the scrubbing liquid (EPA, 1996a; EPA, 1996b). VOC Control: ,Absorption, is a commonly applied operation in chemical processing.

The flow rate of the treated ,flue, gas was around 300 Nm3/h, so the pilot-plant capacity is one of the largest with respect to other published studies on a pilot-plant wet FGD. The tests were carried out at an SO2 inlet ,concentration, of 2000 ppm by changing the recycle slurry pH to around 4.8 and the L/G ratio to between 7.5 and 15.
