خلاصه مقاله:
Biogas is a clean environment friendly fuel that is produced by bacterial conversion of organic matter under anaerobic (oxygen-free) conditions. Membrane processes havebeen identified as one of the most effective means for upgrading biogas and this topic has already received considerable attention the production of methane through themicrobial degradation of organic wastes. This strategy does indeed offer the possibility ofusing a large variety of renewable feed stocks (food and agricultural wastes, manure, crop residues, municipal and industrial wastewater, landfill, etc.) for an alternativeproduction of gaseous fuel. Several analyses have also shown that biomethane production through energy crops can lead to larger yields in Joule per hectare ascompared to for instance ethanol or biodiesel. The new membrane material was resistantto the small concentrations of sour gases and assured the reduction of H2S and water vapour concentrations, as well. The required enrichment was achieved in the singlemodule, however to prevent CH4 losses the multistage or hybrid systems should be used to improve process efficiency. In the paper the results of the tests of the CH4 enrichment was showed that using the capillary module with glassy polymers, such as polyimidemembranes, it was possible to achieve the enrichment of CH4 from the concentrations of 55–85% up to 91–94.4%.
