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.
