Experimental test with polymeric membrane for the biogas purification from CO2 and H2S

The process chosen is able to upgrade biomethane for different inlet conditions assessing the efficiency of this technology in the presence of pollutants typical of a biogas from anaerobic digesters fed by animal waste and biowaste. Specifically, the experimental tests with binary mixtures CH4/CO2 in the range of typical composition, are carried out tests in order to evaluate the performance of the membrane in the presence of H2S; moreover the results are compared with a prediction model showing a good agreement between experiments and simulation results in terms of biomethane purity and yield.
