Abstract

PURPOSE: To carry out the absorption reaction with a high absorption rate and the exidation reaction, producting gypsum, at the same time, making pH unnecessarily low, by maintaining pH of slag (containing CaO 40 W 50%), used for the wet process desulfurization of exhaust gas, slurry in a fixed range.
