一种醇醚胺类气体净化剂及其应用
摘要：
本发明公开了一种醇醚胺类气体净化剂及其应用，所述的醇醚胺类气体净化剂为N,N-二甲胺基多乙二醇甲醚中的一种或几种混合物，或为N,N-二甲胺基多乙二醇甲醚与聚乙二醇二甲醚的复配物；所述的N,N-二甲胺基多乙二醇甲醚结构通式为：(CH3)2N(CH2CH2O)nCH3，其中n=1、2、3、4。本发明的N,N-二甲胺基多乙二醇甲醚，具有较低的粘度和强的空间位阻效应，在改善酸性气体吸收能力、提高吸收选择性等方面起到一定的增益促效作用，是新型胺类脱硫脱碳溶剂，具有化学稳定性好，不易降解变质，对装置腐蚀较小等优点，在酸性气体净化领域可以与NHD溶剂相媲美，在脱碳脱硫应用中具有很好的环保效益和经济效益。
摘要（英）：

The invention discloses an alcohol ether amine gas purifying preparation and applications thereof. The alcohol ether amine gas purifying preparation is one or a mixture of a plurality of ingredients selected from N, N-dimethylamino poly(ethylene glycol) methyl ethers, or a compound of N, N-dimethylamino poly(ethylene glycol) methyl ethers and polyethylene glycol dimethyl ether; the structural general formula of the N, N-dimethylamino poly(ethylene glycol) methyl ethers is (CH3)2N(CH2CH2O)nCH3, wherein n=1, 2, 3, 4. The N, N-dimethylamino poly(ethylene glycol) methyl ethers are low in viscosity, possess excellent steric-hinerance effects, posses certain promotion effects on improving acidic gas absorbing ability and improving absorption selectivity, are novel amine desulfuration and decarbonization solvents, possess excellent chemical stability; degradation is not easily caused; and corrosion on equipment is low; the performance of N, N-dimethylamino poly(ethylene glycol) methyl ethers is comparable to that of NHD solvent; and the alcohol ether amine gas purifying preparation possesses excellent environment protection benefits and economic benefits in decarburization desulfurization applications.
