南化集团研究院开发的NCMA脱碳溶剂在中国石化武汉分公司干气提浓装置上进行工业应用，结果表明：与原设计的 MDEA脱硫溶剂相比，采用NCMA脱碳溶剂，胺液吸收CO2的能力大幅提高，在处理量相当的情况下，干气提浓装置提浓干气吸收塔的胺液循环量由33 t∕h 下降到14 t∕h；胺洗后提浓干气中CO2体积分数低于50μL∕L，溶剂的 H2 S负荷以及脱除硫醇的能力均有所提高。

The industrial application of NCMA solvent for CO2 removal in dry gas enrichment unit in Wuhan Co.SINOPEC was reviewed.The results show that the NCMA solvent can improve CO2 ab-sorption performance compared with MDEA. At the same throughput of the unit,the recycling amine solution rate to the dry gas absorption tower is dropped from 33 t∕h of MDEA to 14 t∕h of NCMA sol-vent and the concentration of CO2 in the treated gas also decreased from 400 μL∕L to less than 50 μL∕L.Meanwhile,the H2 S loading of NCMA solvent and ability to remove mercaptan are higher than MDEA.Finally,the alkali consumption,electricity consumption and emissions of alkali waste of the process are all reduced by using NCMA solvent instead of MDEA.
