由奥特洛夫公司负责设计和施工,普苏尔气体加工和石油化学公司经营的一座美国最大的硫磺回收装置于1981年10月在密西西比州杰克逊城开工投产。硫磺回收装置前面的气体处理装置采用环丁砜法脱硫,每天处理100百万立方英尺的含硫气体,每天出售净化气55百万立方英尺。硫磺回收装置后面设有尾气处理装置采用比文尾气处理方法,提高硫磺回收率和防止空气污染,硫磺的总产量达到1300吨/日。硫磺回收装置的辅助
Otellov was responsible for the design and construction. The largest sulphur recovery unit operated by PSO Gas Processing and Petrochemical Company was started and put into production in Jackson City, Mississippi in October 1981. The gas treatment unit in front of the sulfur recovery unit uses sulfolane desulphurization to treat 100 million cubic feet of sulfur-containing gas per day and sells 55 million cubic feet of purified gas per day. The tail gas treatment device behind the sulfur recovery device adopts Bevan tail gas treatment method to increase the sulfur recovery rate and prevent air pollution. The total output of sulfur reaches 1300 tons/day. Sulphur recovery device
