Abstract
Methane is one of the important greenhouse gases and methane is the major component of the biogas. A multiple stage membrane process was developed and analysed with the numerical analysis so that the mole fraction of methane in the final product could be kept higher than 0.95 and simultaneously the recovery of methane was also maintained higher than 99% from the biogas using 3 polysulfone hollow fiber membrane modules which were properly connected. As the feed pressure of the biogas, the mole fraction of methane in the biogas and the membrane area in the membrane module are increased, the methane mole fraction of the final product are found to be increased. However, a proper membrane area in the module should be carefully selected in order to achieve the satisfactory goal of 0.95 mole fraction of methane and 99% recovery of methane from the biogas. Even if the multiple membrane process is utilized with the properly selected membrane modules, the limited operating ranges have to be applied in the following parameters : the feed pressure, the flow rate, the mole fraction of methane in the biogas to get both the target methane concentration and the recovery rate of methane.
