【Abstract】 The wet FGD process with waste marble was studied experimentally, and the mass transfer reaction mechanism was analyzed. Main parameters including liquid/gas ratio, pH value of the absorbent slurry and inlet SO 2 concentration, etc. affecting SO 2 removal efficiency were studied for the process. The results show that the suitable operating conditions were recommended as follows: pH 0=5 5～6 5, L/G=3L/m 3, a =2%; the sulfur dioxide removal efficiency can reach more than 60% when the inlet SO 2 concentration was 1000ml/m\+3.In addition, the industrial application potential for this process was discussed.更多还原
