摘要
本文从两方面扼要评述了近年来克劳斯硫磺回收工艺技术出现的很多新进展.一是改进回收工艺本身以提高硫收率或装置效率,包括应用新型催化剂、贫酸制硫技术、氧基硫磺回收工艺等;二是发展尾气处理技术,主要包括低温克劳斯反应和转化-吸收反应两大类.
The new developments in Claus sulfur recovery and relate technologies since 70's are briefly reviewed in two aspects.One is improving the sulfur recovery technology itself to increase the sulfur recovery or unit efficiency,including the use of new catalysts,methods of sulfur recovery from lean acid gas,oxygen-Based sulfur recovery technology and so on.The other is developing tail gas treatment technique,including mainly the sub-dewpoint Claus eraction and conversion-absorption reaction.
