遂宁市天然气净化厂尾气排放和变化趋势研究

Study on Changing Trend of Exhaust Emissions of Natural Gas Purification Plants in Suining

为掌握遂宁市天然气净化厂尾气排放和厂界周边环境质量状况,采用现场调查和监测相结合的方式,监测了净化一厂和净化二厂硫磺回收装置尾气排放和厂界周边环境空气质量,总结出了硫磺回收装置尾气中二氧化硫的季度和年度变化规律。结果表明:遂宁市天然气净化厂尾气排放能够达到标准要求,净化一厂二氧化硫排放浓度高于净化二厂,冬春季节浓度高于夏秋季节,二氧化硫排放浓度逐年降低,周边环境空气质量未受到明显影响。

In order to grasp the exhaust emissions and the ambient air quality around the plant boundary of Suining natural gas purification plant,the exhaust emissions and ambient air quality around the plant boundary of purification plant No.1 and purification plant No.2 were monitored by means of field investigation and monitoring,and the quarterly and annual changes of sulfur dioxide in the exhaust gas of sulfur recovery plant were summarized.The results show that the exhaust emissions of Suining natural gas purification plant can meet the standard requirements.The sulfur dioxide emission concentration of purification plant 1 is higher than that of purification plant 2,and the concentration of sulfur dioxide emission in winter and spring is higher than that in summer and autumn.The sulfur dioxide emission concentration decreases year by year,and the ambient air quality is not significantly affected.
