Abstract
A method of PSA gas separation for a gas mixture containing hydrogen and hydrocarbon impurities. The gas mixture is put in contact with silica gel and activated carbon so as to adsorb the impurities in the gas mixture. Hydrogen rich and waste gas flows are produced. The waste gas flow may be sent to the combustible network of a petrochemical site, without having to make a pressure adjustment to the waste gas.
