摘要

醇胺溶液吸收CO2是沼气提纯领域重要的研究课题。在实验填料吸收塔中，以NaOH水溶液吸收低浓度CO2的实验结果估算了填料的有效相界面积，建立了乙醇胺（MEA）溶液吸收高浓度CO2增强因子的数学模型，并从数学模型和实验的角度研究了MEA浓度、进气流率、CO2浓度等工艺参数对MEA吸收CO2增强因子的影响。结果表明，增强因子数学模型计算值与实验值能够良好吻合，MEA吸收CO2化学反应增强因子随进气CO2浓度增加而降低，随MEA浓度增加而增加，随进气流率增加而减小。

Abstract

CO2 absorption by aqueous alkanolamine solution is an important research topic in the field of biogas purification. A packed tower was used to investigate the CO2 absorption by ethanolamine (MEA) solutions. The effective gas-liquid interfacial area was calculated from the experimental results of CO2 absorption by sodium hydroxide aqueous solutions. A mathematical model was proposed to calculate the enhancement factor of the CO2 absorption of relatively high concentration by MEA aqueous solutions. The influence of various technological parameters on the enhancement factor of CO2 absorption by MEA was analyzed from the two aspects of mathematical model and experiment

including gas flow rate

MEA concentration and CO2 concentration. The results show that the model predictions are in good agreement with the experimental values. The enhancement factor of CO2 absorption by MEA increases with the increment of MEA concentration and decreases with the increment of CO2 concentration and gas flow rate.
