Cover Story: The continuous transition towards renewable energy and sustainable processes requires the use of technologies and raw materials alternative to conventional ones. In this regard, membrane processes can be adopted for gas purification of H2-containing mixtures to obtain gas streams with high levels of purity. This work investigates the potential of inorganic membranes to purify H2 and CH4 from their binary mixture by a simulation analysis, offering single- and multistage configurations that include the use of Pd-Ag and zeolite membranes. The use of the metallic membrane guarantees extremely pure H2, while simultaneously recovering CH4 at a concentration of 95%. The economic evaluation reveals the good potential of the proposed solutions, since the predicted values of profit and net present value are estimated to be positive. View this paper
