| 摘 要： | 普光气田的天然气具有高含H2S和含CO2及有机硫的特点，天然气净化难度大。为满足高含硫天然气净化的要求，普光天然气净化厂采用了MDEA法脱硫脱碳、TEG法脱水、常规Claus硫磺回收、加氢还原吸收尾气处理的天然气净化工艺路线。同时，在国内首次应用了气相固定床水解脱除羰基硫（COS）、中间胺液冷却、MAGR液硫脱气等国际先进的天然气净化新工艺和专利技术，通过不断地摸索及优化工艺参数，解决了原料气脱除有机硫、CO2选择性吸收、液硫深度脱除H2S等技术难题；还应用了溶剂串级吸收和联合再生工艺、能量回收利用等多项技术，通过优化调整胺液循环量、降低能耗等手段，降低了操作费用。高含硫天然气净化新工艺技术应用于普光气田后，净化装置运行稳定，净化气质量超过设计要求，达到了国家标准一类气的指标。

| Abstract: | Natural gas in the Puguang Gas Field contains such a high content of H2S,CO2 and organic sulfur that its conditioning and processing will be a great difficulty.To meet the requirement of high-H2S gas sweetening,the Puguang Natural Gas Conditioning Plant has adopted some conventional methods like acid gas removal by MEDA,gas dehydration by TEG,Claus sulfur recovery,and tail gas treatment by hydrogenation and reductive absorption.Meanwhile,with several international advanced technologies and patents being int... |
