Comparison of different solvents in simulation of CO2 removal via hollow fiber membrane

CO2 gas possess a key role in the environmental pollution, rise of global warming. Due to its corrosive effect through the gas transit, the charge of transportation are increased. Therefore, CO2 removal seems to be necessary in the oil, gas and petrochemical industries. The aim of study is to evaluate the effect of gas, distilled water and mono-ethanol amine flow rates on CO2 removal process. The modules, solvents and gas flow rates were introduced into the Comsol software. The higher efficiency of CO2 removal was attributed to the high solvent flow rate. However, the reduction of gas flow rate results in the enhancement of CO2 removal.Consequently, CO2 removal via hollow fiber membrane could be improved by mono-ethanol-amine as solvent with low gas flow rate. In comparison of the experimental data, the simulation results revealed a great accuracy that results in the time saving and reducing the cost.
