METHOD FOR PRODUCING BIOMETHANE BY PURIFYING BIOGAS FROM NON-HAZARDOUS WASTE STORAGE FACILITIES AND FACILITY FOR IMPLEMENTING THE METHOD

A method for producing biomethane by purifying biogas from non-hazardous waste storage facilities involves compressing the initial gas flow, introducing the gas flow to be purified into at least one adsorber loaded with adsorbents capable of reversibly adsorbing the VOCs, and subjecting the VOC-depl...

Zusammenfassung:	A method for producing biomethane by purifying biogas from non-hazardous waste storage facilities involves compressing the initial gas flow, introducing the gas flow to be purified into at least one adsorber loaded with adsorbents capable of reversibly adsorbing the VOCs, and subjecting the VOC-depleted gas flow to at least one membrane separation step in order to partially separate the CO2 and O2 from the gas flow. The method also involves introducing the retentate from the membrane separation step into at least one adsorber loaded with adsorbents capable of reversibly adsorbing the major portion of the remaining CO2, subjecting the CO2-depleted gas flow exiting the adsorber loaded with adsorbents capable of reversibly adsorbing the major portion of the remaining CO2 to a cryogenic separation step in a distillation column in order to separate the O2 and N2 from the gas flow, and recovering the CH4-rich flow from the cryogenic separation step.
