Process for producing purified hydrocarbon gas from a gas stream comprising hydrocarbons and acidic contaminants, which process comprises the steps of : (a) contacting the gas stream with one or more membranes to obtain a hydrocarbon-rich retentate and a acidic contaminant-rich permeate; (b) cooling the hydrocarbon-rich retentate in a cooling stage to form a mixture comprising solid and/or liquid acidic contaminants and a vapour comprising vaporous hydrocarbons; (c) separating solid and/or liquid acidic contaminants from the mixture, yielding the purified hydrocarbon gas.
