Abstract:

As the fossil fuels diminish and the prices soar, the world is turning its attention to renewable fuels as an alternative to reduce its dependence on fossil fuels. Biogas is one of the renewable source of energy. However, to be used as a fuel, it needs to be purified and upgraded to meet the standards of the fuels set worldwide. This includes removal of impurities like Sox, Nox and Cox. Carbon dioxide removal is done to increase the methane content in biogas and bring it at par with other fossil fuels such as natural gas. There are several methods of removal of carbon dioxide such as membrane separation, adsorption, absorption etc. Pressure swing absorption and membrane separation have their limitations due to cost issues. Absorption is one of the best ways for carbon dioxide removal with high carbon dioxide removal as well as due to the reason that solvent can be recovered. This paper presents a description of Carbon dioxide removal process that has been simulated with the process simulation tool Aspen Plus. To achieve high CO2 removal, different parameters and other operating conditions were varied and simulated on Aspen Plus model. The effect of concentration on absorption and CO2 removal are studied. The absorption rate, absorption capacity, and loading of CO2 absorption are investigated
