The process is simple, no need for additional consumption of fresh water and absorbent, no by-products and waste, easy to maintain, low investment cost, high desulfurization rate; however, the process has problems such as equipment is easy to corrode and block, so overflows in the process of desulfuration sea water aeration, large floor area, and high sulfur coal flue gas desulfurization is difficult to achieve standard emission, etc. However, the process has equipment is easy to corrode and easy to be discharged In the process of seawater aeration, SO2 overflows, covers a large area, and the high sulfur coal flue gas desulfurization is difficult to reach the discharge standard
