摘　　要：为了满足工业及日常应用的需求,原料天然气要进行净化处理。有机硫是天然气中一种较难脱除的杂质,不但在天然气开采、处理和储运过程中会造成设备和管线腐蚀,用作燃料时还会带来环境污染,危害用户健康。近年来,国际社会对商品天然气中有机硫含量的要求愈来愈严格,溶剂法脱除天然气中有机硫工艺研发受到了普遍关注。通过总结各类文献中常用的脱除天然气中有机硫的方法及其机理,讨论了物理溶剂法、化学溶剂法及混合溶剂法脱除天然气中有机硫气体的优缺点,阐述了未来天然气中有机硫脱除技术的发展趋势。In order to meet the needs of industrial and daily application, raw natural gas must be purified. Organic sulfur is a kind of impurities difficult to be removed from natural gas and it will not only corrode equipment and pipelines in exploitation, processing, storage and transportation process, but also result in environmental pollution and endanger person's health when used as fuel. In recent years, the international communities have increasingly strict requirements for organic sulfur content in commercial gas, close attention is paid to the research and development of solvent method removal of organic sulfur in natural gas. Introduced are organic sulfur removal methods commonly used at present and their mechanisms, analyzed are advantages and disadvantages of physical, chemical and mixed solvent desulfurization methods respectively and finally predicted is the development trend of organic sulfur removal technology in the future.
