硫磺回收装置尾气处理技术比选
|
摘要
为应对环保标准不断升级,硫磺回收尾气处理技术不断进步。在分析了硫磺回收装置尾气达标的技术难点的基础上,介绍了LS-DeGAS、烟气碱洗技术、氨法尾气脱硫技术、有机胺脱SO_2尾气处理(Cansolv SO_2洗涤)技术、超优Claus+烟气碱洗技术等几种典型技术的优缺点及适应性,并针对企业现状及环境约束,在统筹考虑装置投资、运行费用和排放指标的基础上,提出选择硫磺回收尾气处理技术的建议。
The continuous upgrading of environmental specifications promotes the technical progress of tail gas sulfur recovery.Based on the analysis of the technical difficulties of sulfur recovery for meeting the specifications of the tail gas,the advantages and disadvantages and adaptability of several typical technologies,such as LS-DeGAS,alkali washing of flue gas,desulphurization of ammonia,Cansolv SO_2 washing using organic amine,as well as super-optimal Claus+ alkali washing of flue gas,were introduced and compared.In view of the current situation of enterprises and environmental constraints,suggestions on technology selection were proposed on the basis of overall consideration of investment,operation cost and emission indexes.
