Title: ASSEMBLY FOR THE PRODUCTION OF METHANE FROM SOIL GAS EMITTED BY DEGASSING ZONES
Abstract:
An assembly for the production of methane comprising at least one methanation reactor (6) suited to convert carbon dioxide into methane by means of catalytic hydrogenation, an electrolyzer device (5) suited to produce the necessary hydrogen to be introduced into the methanation reactor (6), collection means (2) for collecting from degassing zones a soil gas comprising carbon dioxide, and a treatment device (3) for desulphurization of the soil gas from the soil collection means (2) and suited to purifying the carbon dioxide to be introduced into the methanation reactor. The electrolyzer device (5) is powered with electric energy from renewable sources.
