Our objective through this work is to purify the biogas produced by a methanisation process in order to be valorized in a cogeneration unit. The studied biogas is mainly composed of methane 60% and carbon dioxide 39%. The treatment will increase the quality of the biogas by decreasing the percentage of CO2, in order to improve the energetic properties of the gas mixture (PCI). Several biogas purification and bio-methane production processes are commercialized. The choice of the technical and economic optimum is strongly linked to the quality and quantity of biogas to be purified, the quality of the desired bio-methane, depends on the type of methanisation, the nature and regularity of the substrate supply, but also on the local conditions of implantation. In this part of our research project, we are interested in the study, dimensioning and modeling of a CO2 capture unit by chemical absorption, constituted by a packed column. The solvent used is the secondary amines in mixture with the primary amines.
