SCOT硫回收尾气处理技术进展及应用

摘要

SCOT （ Shell Claus Off-gas Treatment） sulfur recovery off-gas treatment technology was an off-gas purification process by which the number of the constructed plants having been built presently in the world was the maximal. Author has introduced the basic principle and process flow of the SCOT technology： has compared the technical characteristic of the low temperature SCOT, super-class SCOT, low sulfur SCOT with the conventional SCOT; has briefly described the technical progress of the SCOT process; has looked ahead its application prospect in China.%SCOT（Sell claus Off-gas Treating）硫回收尾气处理技术是目前世界上装置建设数量最多的尾气净化工艺。介绍了SCOT技术的基本原理和工艺流程;对比了低温SCOT、超级SCOT、低硫SCOT与常规SCOT的技术特点;简述了SCOT工艺的技术进展;展望了其在国内的应用前景。
