Biogas is a developing alternative energy source produced from the anaerobic digestion of organic matter by bacteria. It is composed of methane and carbon dioxide (CO2) with trace amounts of hydrogen sulfide (H2S). The presence of CO2 decreases the energy yield from the combustion of biogas. Past studies on biogas purification have used expensive and environmentally harmful chemicals to purify biogas. This study will involve the construction of a biogas purification system that utilizes sodalime to remove carbon dioxide from biogas by absorbing in it through chemical reaction. This method has the distinct advantage of being simple and easy to use in rural areas. It is expected to purify biogas to a degree similar to that of the most commonly used chemical methods while increasing cost-efficiency by this method.
