Abstract

Biogas is a renewable energy source that can be used as an alternative to fossil fuels, given the increasing exploration and development of non-renewable energy sources. Biogas is processed through an anaerobic digester with the help of microorganisms in the reactor. However, the biogas production process produces acid gases such as CO2 and H2S which can reduce the quality of biogas and cause corrosion. Therefore, a purification process is carried out by the absorption method in a pressurized column called a scrubber. This purification process use potassium carbonate and monoethanolamine as an absorbent aims to reduce the acid gas content in biogas to produce biogas that is more environmentally friendly. The addition of absorbent monoethanolamine can increase the percentage of CO2 gas removal and potassium carbonate can increase the percentage of H2S gas removal.
