三乙醇胺与烯胺混合胺液脱碳性能及配比优选实验研究
Experimental study on performance and proportion optimization of TEA+enamine mixed solution for natural gas decarburization
摘要
Abstract
Decarburization by mixed amine solution has been widely used because of its good purification ability and low energy consumption. MDEA is used as the main absorbent in the mixed amines. In order to meet the demands of finding economical and highly efficient new absorbents,TEA was selected as the main amine solution for experimental study in this paper,which was tertiary amine,the same as MDEA. Based on the study of TEA solution reaction mechanism,the absorption and desorption performance of the TEA+DETA/TETA mixed amine solutions with different concentrations were studied experimentally,and the better amine solution was selected based on comprehensive performance. Enamines could promote absorption ability , but it would reduce desorption performance. The absorption and desorption performance of the TEA+DETA mixed amine solution was better than the TEA+TETA mixed amine solution. The mixed amine solutions with DETA concentrations of 1mol/L and 0.6mol/L were better. According to cycle experiments,the comprehensive performance of the mixed amine solution with DETA concentration of 1mol/L was the best.关键词
