摘要

以水（H2O）、氢氧化钠（NaOH）、氨基乙酸钾（GLY）、氨基乙酸钾—哌嗪（GLY-PZ）水溶液为吸收剂，研究了疏水性聚偏氟乙烯（PVDF）中空纤维膜接触器分离CO2/N2模拟烟气中CO2的技术，具体考察了流动方式、气液流率、吸收液浓度和温度、原料气CO2浓度、填充密度等对膜接触器吸收效率的影响。结果表明，气液逆流的腔流程模式具有较高的分离效率。不同吸收剂的分离性能为：NaOH > GLY-PZ > GLY > H2O。温度对各种吸收剂的影响随其种类不同而有所差异。膜接触器对烟气CO2的分离效率随填充密度、吸收液浓度和流率的提高而增大，随气体流率及其中CO2浓度的增大而减小。

Abstract

Polyvinylidine fluoride (PVDF) hollow fiber membrane contactors were applied to the separation of carbon dioxide (CO2) from flue gas using water (H2O)

sodium hydroxide (NaOH)

potassium glycine (GLY) and potassium glycine-piperazine (GLY-PZ) solution as dedicated absorption liquid. Effects of flow mode

flow rate of feed gas and absorbent solution

absorbent concentration and temperature

feed gas concentration and packing density on the removal rate and total mass transfer coefficient were investigated in detail. Results showed that the lumen side process with two phases flowing countercurrently had the highest separation efficiency. The absorption performances of four kinds of absorbents were in the sequence of NaOH> GLY-PZ> GLY> H2O. The effect of temperature on various absorbent was different. The separation efficiency of CO2 can be enhanced by increasing of the packing density

concentration and flow rate of absorbent solutions while weakened with increasing of the concentration and flow rate of flue gas.
