摘要

研究了CO2在中空纤维膜吸收器中的吸收过程.以非湿膜操作为例，建立了中空纤维膜吸收器的传质模型，用T-型差分法模拟了CO2在水、NaOH、乙醇胺(MEA)、2-胺基-2-甲基-1-丙醇(AMP)水溶液中的吸收.研究了AMP-MEA混合有机胺水溶液吸收CO2的过程.对于CO2在0.6mol8226;L-1 NaOH水溶液中的吸收，比较了模拟结果与实验数据，二者符合较好.

Abstract

The process of CO2 absorbed in a hollow fiber membrane absorber was studied. For the non-wetted mode

the mathematical model of mass transfer in the membrane absorber was derived. The solution method for nonlinear partial differential equations was given by using T-model difference scheme. For water

NaOH

monoethanolamines (MEA) and 2-amino-2 -methyl-1-propanol (AMP) as absorbents

the process of CO2 absorbed in hollow fiber membrane absorber was simulated. In addition

the absorption of CO2by an aqueous mixture of AMP-MEA was also investigated. For CO2 absorbed into 0.6 mol8226;L-1 NaOH solution

the result of simulation agreed well with the experimental data.
