三乙醇胺+哌嗪混合胺液的脱碳性能及配比优选
Decarburization performance of the mixed amine of TEA and PZ and their ratio optimization
摘要
Abstract
Amine decarbonization is widely used in natural gas pretreatment on account of its good removal result and low energy consumption. According to the survey,MDEA is widely used as the main absorbent in mixed amine solutions. In order to find new absorbents,which are economic and highly efficient,TEA is selected as the main amine solution for experimental study in this paper. Both TEA and MDEA are tertiary amines. According to the reaction mechanism of TEA solution,PZ is selected as the additive to study the decarburization performance of TEA+PZ mixed amine solution. The absorption, desorption and cycle performance of TEA+PZ mixed amine solution with different ratios are investigated. The experimental results show that the absorption performance of TEA+PZ mixed amine solution was improved when the amount of PZ increases,but this phenomenon will not be obvious with the further increase of PZ. The addition of PZ has no significant effect on the desorption performance of TEA.关键词
