烟气脱硫技术的发展及其应用前景

烟气脱硫是目前世界上唯一大规模商业化应用的脱硫方式。本文综述了脱除烟气中SO2 的一些主要技术 ,包括干法、半干法、湿法以及它们的优缺点 ,其中湿法烟气脱硫应用最为广泛。同时对我国湿法、半干法、干法中的几种脱硫技术进行了比较 ,得出湿法烟气脱硫的脱硫效率最高 ,可高达 90～ 95 % ,半干法次之。湿法烟气脱硫的烟气处理量也最高 ,并且有些技术已经进行了工业化应用。但是湿法烟气脱硫技术的运行费用比较高

Development and Applied Prospect of Process of FGD

The process of FGD is the only desulfurization method applied in commerce on a large scale in the world.The paper summarized the major processes of FGD,including wet desulfurization, dry and semi-dry desulfurizing,even their advantages and disadvantages.The application of wet desulfurization is most extensive.At last,the comparison of some processes of FGD is carried out.The result indicates that the desulfurizing efficiency of wet desulfurization is the highest to 90～95% and the dry desulfurizing takes second place.The treatment capacity of wet desulfurization is the largest and it has been used in industry,but its operational expenditure is higher.
