中文摘要：目前国内天然气净化主流设施包括脱硫单元、脱水单元、硫磺回收单元、尾气处理单元、酸性水汽提单元。在生产过程中,不可避免的会产生如尾气吸收塔顶尾气、液流池抽空器废气、地下罐废气等含硫尾气，且均通过烟囱等形式排放至大气，对环境、空气造成严重污染。随着环境问题越来越受到国家和公众的关注，各地积极开展清洁生产、绿色生产、节能降耗等措施，以响应国家号召。因此，对影响烟气SO2排放浓度的主要因素现场进行调研、分析、实践得出解决措施，以达到清洁生产，减排增效的目的。
英文摘要：At present,domestic natural gas purification facility is made up of desulfurization unit,dehydration unit,sulfur recovery unit,tail gas treatment unit,sour water stripping unit.In the production process, the device will inevitably produce tail gas exhaust,including gas of absorption tower,tail gas of liquid sulfur pool evacuator,tail gas of underground gas tank.And go through the chimney or other form of atmospheric emission.With the ongoing attention of environmental problem raised from nation and public.In response to the national call all places actively should take some measures of clean production,green production,energy saving and so on.Therefore,it is crucial to reduce exhaust concentration of SO2 emission, The main factors of affecting the concentration of flue gas SO2 emissions field research，analysis and practical solutions, purposes of emission reduction and synergism.
