摘　　要：介绍了硫化氢酸性气干、湿法制酸的技术特点,认为湿法制酸优于干法。对目前国内外应用广泛的3种湿法制酸技术进行了比较。重点论述了丹麦WSA、国产化湿法制酸工艺的技术原理、工艺流程、技术特点及在国内的应用状况、技术发展前景。国内湿法制酸工艺也已成熟,工艺运转率、酸回收率有了较高水平。The technical characteristics of sour hydrogen , sour gas, dry and wet acid making are introduced. It is considered thatacid making by wet process is better than dry process, and three methods of wet process of acid making which are widely used at homeand abroad are compared. The technical principle,technological process, technical characteristics, domestic application and technical development prospect of WSA process in Denmark are discussed in detail. At present,the domestic wet gradually mature, and the process operation rate is improved and acid making rate.

关 键 词：硫化氢酸性气硫回收湿法制酸比较WSA工艺国产化
