Abstract

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.

Key words: membrane contactor, membrane-base absorption, simulation, transfer
