摘要:

随着近年来环境形势的日益严峻以及人们环保意识的增强,国家颁布了更加严格的污染物排放标准,对硫磺回收装置尾气的排放要求也相应提高,进一步推动了尾气处理工艺的发展。SSR工艺作为一种兼具环保效益和经济效益的尾气处理工艺应运而生,在对比SSR工艺与SCOT工艺、Super SCOT工艺、RAR工艺、HCR工艺4种主要还原吸收工艺的基础上,重点介绍了SSR工艺的基本原理、技术特点及在不同硫磺回收装置中的应用,并对其应用前景进行了展望。 

Abstract:

In recent years, as the situation of environment becomes serious and the consciousness of environmental protection is enhanced, more strict standards for pollutants discharge were issued. The emission requirements of tail gas from sulfur recovery unit are accordingly improved, which further promote the development of the tail gas treatment process. SSR is a tail gas treatment technology with both environmental and economic benefits. The SSR technology and other four kinds of reduction-absorption technology, which include SCOT, Super SCOT, RAR and HCR, are compared. The principle, technical characteristics and application in different sulfur recovery devices are mainly introduced, and the application prospect is forecasted.
