Document Type and Number:
WIPO Patent Application WO/2023/222485
Kind Code:
A1
Abstract:
The invention relates to a plant and method for producing deoxygenated biomethane (10) having an oxygen concentration below a determined threshold, in particular below 100 ppm, from biogas (1), the plant comprising: - a membrane-permeation treatment unit (5) which is able to produce biomethane (9) and is configured to produce biomethane having a molar concentration below a first determined threshold, for example less than 5% CO2 and less than 1% O2, in particular less than 3% CO2 and less than 0.7% O2, from a stream of biogas having a CO2 concentration above a second threshold, for example from 15 to 60% carbon dioxide, - a compressor (2) configured to compress the biogas (1), and - at least one catalytic reaction unit (3) comprising at least one bed of at least one oxidation catalyst configured to deoxygenate the biogas (1) and/or the biomethane (9) and/or the partially purified biogas (7).
