摘要:

降低ＳＯ２排放是硫回收行业关注的课题，是各国环境立法的重要内容，目前技术水平已达到能满足对ＳＯ２排放的任何限制。Ｃｌａｕｓ法是硫回收技术的基础。提高酸气质量、配风质量、催化剂质量及优化操作、设计，是Ｃｌａｕｓ法硫回收效率最佳化的关键，是尾气处理的基础及先决条件。技术经济及环境的综合因素促进了高效率硫的回收技术的发展，即Ｃｌａｕｓ法与尾气处理技术的结合，８０年代以来开发了ＭＣＲＣ和Ｓｕｐｅｒｃｌａｕ

Abstract:

Reduction of SO2 emission is a topic attracting attention of sulfur recovery industry. It is also an important content,in the environmental laws and regulations of every country over the world. The present technical level can meet the limits on SO2 emissi
