- 摘要:
- 为了满足越来越严格的环保法规要求，适应石油资源日渐枯竭的形势，天然气在能源结构中所占比例逐渐增加，天然气净化技术得到了长足发展。介绍并总结了常用的天然气脱硫脱碳工艺：化学溶剂法，包括常规胺法、以MDEA为代表的选择性胺法；物理溶剂法；化学-物理溶剂法，以砜胺法为代表；直接转化法及其它方法。在对各种方法适用条件进行说明的同时，通过对比得出相应方法的优缺点。MDEA由于其普适性和低能耗性得到了最为广泛的应用。结合环保法规要求对天然气净化工艺的发展趋势作了预测，认为物理方法将成为工艺开发者的首选。
In order to satisfy more and more strict requirements in environment protection laws and regulations and adapt to oil resource exhaustion trend，the ratio of natural gas in energy structure increases gradually and natural gas purification technologies have been developed significantly. Introduced are natural gas desulfurization and decarbonization technologies used frequently at home and abroad： chemical solvent method，including conventional amine method and selective amine method，physical solvent method，chemical-physical solvent method，direct conversion method and other methods. Analyzed are applicable scopes of different methods and compared are their advantages and disadvantages. In general，MDEA is used very widely due to its universality and low energy consumption. Predicted is the development tendency in natural gas purification technologies according to requirements in environmental protection and it is believed that the physical method will become the first choice of process developers.
