摘　　要：天然气开采过程使用三甘醇脱水装置吸收脱出天然气中的水分,其精馏柱尾气含有挥发性有机物(VOCs),目前主要采用分离吸附技术、焚烧炉焚烧和引射增压回收技术进行尾气处理。文章分析各类尾气处理技术的工艺流程、应用实例,对比了各类技术的优缺点、污染物排放和资源利用情况,推荐通过尾气治理实现VOCs减排和资源回收利用的水引射增压回收技术。In the process of natural gas exploitation,the triethylene glycol dehydration device is used to absorb the water in the detached natural gas,and the exhaust gas of the rectification column contains volatile organic compounds,which are mainly treated by separation and adsorption technology,incinerator incineration and induced pressurization recovery technology.This paper delves into a comprehensive analysis of the process flow and application examples of various exhaust gas treatment technologies.It meticulously compares the strengths and limitations inherent to each technique,evaluating their efficacy in terms of pollutant emission reduction and resource utilization.and recommends the water induced pressurization recovery technology to achieve volatile organic compound emission reduction and resource recovery through tail gas treatment.
