摘要针对硫磺回收装置烟气中SO，排放问题，指出烟气中SO：主要有液硫脱气、加氢还原吸收尾气及其他非共性原因3个来源，提出了根据不同来源分别处理以降低排放烟气中总SO2质量浓度的对策，形成了天然气研究院硫磺四收及加氢还原吸收尾气升级达标核心技术，主要包括H,S深度脱除溶剂CT8-26、钛基硫磺回收催化剂CT6-8和新型加氢还原吸收尾气水解催化剂CT6-11B，造用于现有带加氢还原尾气处理的硫磺回收装置，特别是具有独立加氮还原溶剂再生的装置，可将硫磺回收及尾气处理装置排放尾气中SO；质量浓度降至100mg/m”以下，为解决硫磺画收装置尾气达标排放问题提供了新的实施方案。

Abstract, Aiming at the emission problem of SO, from the sulfur recovery unit, it pointed out that the SO, in flue gas is mainly from 3 sources, including liquid sulfur degassing, hydrogen reduction & absorption tail gas,and other non common reasons.According to different sources, the countermeasures to reduce the total SOs emission concentration in flue gas were put forward and the Research Institute of Natural Gas Technology emission reduction technology were invented. The technology mainly includes H, S deep removal solvent CT8-26, titanium based sulfur recovery catalyst CT6-8 and new hydrogenation reduction &. absorption hydrolysis catalyst CT6-11B, The technology is applicable to the existed sulfur recovery unit with hydrogen reduction tail gas treatment, in particular which has an independent hydrogenation reduction solvent regeneration device, It can reduce the SOs mass concentration in tail gas exhausted from sulfur recovery unit to lower than 1oo mg/m'and provide a new solution scheme for tail gas emission to the standard of sulfur recovery device.
Key words: sulfur recovery, emission reach standard, tail gas,H, S, reduction absorption
