硫回收尾气处理工艺分析与选择

简述了硫回收尾气处理工艺的发展概况和技术进展,介绍了国内应用较多的几种尾气处理工艺:SCOT工艺、超级Claus工艺、RAR工艺、SSR工艺和氨法工艺;并对氨法工艺的3种方案进行了详细对比分析;通过对比可知,在有锅炉烟气氨法脱硫装置作依托的前提下,氨法工艺的方案三具有投资省、操作费用低、占地面积小的优势。

Tail Gas Treatment Process for Sulfur Recovery

The development and philosophy of the tail gas treatment process for sulfur recovery was briefed, and some commonly used domestic tail gas treatment processes were introduced, namely, SOCT process, super Claus process, RAR process, SSR process and the ammonia process. The three schemes of the ammonia process were introduced in detail, and comparisons and benefit analysis were made on the last two schemes. The technical data concerning some domestic tail gas treatment processes were analyzed, and the comparison between various processes showed that the ammonia pro- cess had the advantages of less investment, less operation cost and less land demand, in case there is an existing boiler flue gas ammonia desulphurization device.
