Summary:A process is provided for purification of biogas to produce biomethane. The biogas is treated in a pressure swing adsorption unit to remove carbon dioxide and water. Other impurities including oxygen, hydrogen and carbon monoxide may be removed by an additional adsorption bed. The adsorption beds may be single stage or two-stage VPSA or PSA adsorption beds. L'invention concerne un procédé de purification de biogaz pour produire du biométhane. Le biogaz est traité dans une unité d'adsorption modulée en pression pour éliminer le dioxyde de carbone et l'eau. D'autres impuretés comprenant de l'oxygène, de l'hydrogène et du monoxyde de carbone peuvent être éliminées par un lit d'adsorption supplémentaire. Les lits d'adsorption peuvent être des lits d'adsorption VPSA ou PSA à étage unique ou à deux étages.
