前言：天然气是世界上最主要的能源之一，我国天然气正处于大规模开发的前夕。 原料天然气中一般均含有硫化氢、有机硫（硫醇类）等杂质．硫的存在造成合成氨工艺中催化剂中毒，因此需将含硫天然气中的硫化氢、有机硫等硫化物脱除，使产品天然气的硫化氢和有机硫含量符合有关技术指标要求，满足生产需要．在天然气化工迅猛发展的今天，天然气脱硫方法也层出不穷．在传统一已醇胺湿法脱硫，氧化锌干法脱硫的基础上，出现了常温氧化铁脱硫，活性炭干法脱硫，分子筛脱硫，DDS生化湿法脱硫等新技术．尽管脱硫新技术的发展，不外乎干法，湿法脱硫．如何根据天然气中硫的含量选择合适的脱硫工艺，对减少装置维护费用，降低生产成本有着重要作用．脱硫的方法很多，本装置选用的流程是湿法MEA溶液洗涤粗脱，串钴钼加氢转化及ZnO精脱硫的办法。本文试着就干法，湿法脱硫的特点进行比较，结合我车间脱硫装置运行情况进行分析总结，尝试找出比较合理的脱硫运行方式，脱硫方法．并对目前出现的一些脱硫新技术作了简要介绍.
