Abstrakt: In this study the enrichment of methane in ventilation air by pressure swing adsorption (PSA) and by membrane separation was investigated theoretically. In the case of the PSA process, which uses Takeda G2X7/12 activated carbon, the impact...

Abstract: An analysis of the possibilities of using existing membrane materials for the separation of methane contained gas mixtures was carried out. A group of materials was selected that could potentially be used for the recovery of methane from mine...

Abstract: An analysis was carried out of the possibility of concentrating methane from a synthetic biogas in an Air Products membrane module. Experimental investigations concerning the permeation of pure gases and mixture of these gases containing 50...

Abstract: Technologies for thermal utilization of ventilation air methane (VAM) require stabilization and/or increasing its concentration. This paper summarizes the results of research conducted at the IICh PAS in the area of adsorption and membrane...

Summary: Decarbonization, minimizing greenhouse gas emissions, circular economy and the waste-to-energy trend lead to increased demand for gas and green energy. The European Biogas Association shows that biomethane gas can cover 30-40% of EU gas demand...

Abstract: The basic aim of this study was to analyze the possibility of using commercial membrane modules in the recovery of methane from ventilation air. Experimental investigations concerning the separation of gaseous mixture containing 0.3 vol.% of...
