Abstract

Purifying biogas from CO2 (carbon dioxide) and H2S (hydrogen sulfide) needs to be done to improve the quality of the biogas in the fuel. The presence of H2S in biogas can cause corrosive to the equipment, in addition to this, H2S is also dangerous for human and animal health. CO2 contained in Biogas is also an impurity that can cause corrosive beside H2S so the contained in biogas is also an impurity that can cause corrosive, so the purification process needs to be done in order to qualify biogas as natural gas which environmentally friendly and safe for health. The basic ingredient of biogas purification using water scrubbers base ingredients are water, which flowed pressurized biogas purification column from the bottom, of the column in order to reduce CO2 and H2S gases. The result of purification by using this method was that the levels of H2S in biogas reduced by 32.8 % while the CO2 content decreased by 21.2 %. It can be concluded that the H2S gas more soluble in the water compared with CO2, as H2S gas has higher efficiency removal from CO2.
