Biogas, along with conventional energy sources, alternative energy is formed from biological feedstock. Biogas mainly composed of biomethane, carbon dioxide, hydrogen sulfide and contaminants. Acidic components and CO2 removing H2S from biogas expedient as to produce biomethane — an analog of natural gas and carbon dioxide for use as a commercial product. To extract the CO2 and H2S from biogas is proposed to use the absorption method using an effective absorbent: 40 % MDEA+10 %+50 % of the IEA H2O. This can significantly reduce energy costs in comparison with aqueous solutions of MEA. Found that to minimize energy extraction process H2S and CO2 from biogas, the pressure in the absorber must be maintained at — 0,26...0,28 MPa in the desorber — 0,16...0,18 MPa, the optimal inlet temperature of the absorbent in the absorber should be 45 °C.
