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 SO2 concentration, etc. affecting SO2 removal efficiency were studied for the process. The results show that the suitable operating conditions were recommended as follows: pH0 = 5.5-6.5, L/G = 3L/m3, a = 2%; the sulfur dioxide removal efficiency can reach more than 60% when the inlet SO2 concentration was 1000 ml/m3. In addition, the industrial application potential for this process was discussed.
