克劳斯硫回收稳定运行因素探讨

Discussion on Stable Operation Factors in Claus Sulfur Recovery

随着我国国民经济的快速增长,我国的煤化工领域也得到了高速发展。同时为了使尾气排放达到国家环保要求,硫回收工艺也在不断的发展进步。目前国内硫回收的主要技术是克劳斯法,此法通常处理含硫化氢为15%-100%的酸性气。本文通过克劳斯硫回收的工作原理、工艺流程,探讨了如何通过工艺控制,进而达到提高硫磺回收率、降低SO2排放的目的。

With the rapid growth of the national economy,our coal chemical industry has been rapid developed.Meanwhile,in order to make emissions meet the national environmental protection requirements,sulfur recovery process also continues to develop and progress. At present,the main technology is the claus process sulfur recovery. This method is usually used to treat the acid gas containing 15% ~ 17% hydrogen sulfide. By analyzing Claus sulfur recovery works and process,process control was discussed to improve the sulfur recovery rate and reduce SO2 emissions.
