摘　　要：地下煤蕴含的资源量十分巨大,地下煤合成气中CO_(2)含量比常规天然中的CO_(2)含量高,传统MDEA脱碳工艺无法较好地使地下煤合成气中的CO_(2)达到天然气净化指标要求。且传统的脱碳工艺再生能耗高,需要大量燃料气为脱碳再生系统提供能量。通过配方溶液筛选、工艺流程优化、关键参数研究等方法开展研究。结果表明,PZ+MDEA配方可明显提高CO_(2)吸收效率,超高CO_(2)含量合成气脱碳优化工艺可实现地下煤合成气脱碳工艺能耗同比下降55%。The underground coal contains a huge amount of resources.The CO_(2) content in the underground coal synthesis gas is higher than that in the conventional natural gas.The traditional MDEA decarburization process can not make the CO_(2)in the underground coal synthesis gas meet the requirements of natural gas purification.In addition,the traditional decarburization process requires a large amount of fuel gas to provide energy for the decarburization regeneration system.The research was carried out by means of formula solution screening,process optimization,key parameters research,etc.The results show that.The PZ+MDEA formula can significantly improve the CO_(2)absorption efficiency,and the optimized process for decarburization of synthetic gas with ultra-high CO_(2)content can realize a 55% year-on-year decrease in energy consumption of the process for decarburization of underground coal synthetic gas.
