摘要: 建立微分方程和阻力方程组合模型,模拟了以MDEA(N-甲基二乙醇胺)为吸收剂,聚丙烯疏水性中空纤维膜接触器吸收H2S的传质过程。采用聚丙烯中空纤维制成膜接触器,以MDEA溶液为吸收剂,进行天然气脱除H2S实验。对实验值与模拟值进行比较。结果表明,以膜组件出口气H2S浓度作为衡量标准,在低气速和低液速的情况下,模型值与实验值符合很好;在高气速和低液速的情况下,实验值高于模型值,但相差不大。该模型能很好地模拟膜基吸收法脱除H2S的过程。

Abstract: A comprehensive model of differential equation and resistance equation is established,by using MDEA (N-methyl diethanolamine) aqueous solution as absorbent and selecting hydrophobic polyacrylic hollow fiber membrane (HFPPM) as a contactor.The model is used to simulate absorption H2S mass transfer process.By using polypropylene hollow fiber membrane as a contactor and MDEA solution as the absorbent,natural gas desulfurization experiment is carried out,and the experimental data is compared with the simulated value.The results show that H2S concentration of module export gas is viewed as a measure,in the low gas-speed and low liquid-speed,the simulated value is in good accordance with the experimental data;in high gas-speed and low liquid-speed,the experimental data is higher than the simulated value but there is only little difference.So the model can simulate a very good film-absorption H2S removal process.
