Process for treating a gaseous mixture under pressure to remove unwanted components from a gas, including methane, ethane, hydrogen, nitrogen, such components as C3, C4 and C5 higher hydrocarbons, hydrogen sulphide and carbon dioxide. The gaseous mixture is fractionated under pressure to remove in bottoms product portions of higher hydrocarbons, hydrogen sulphide and carbon dioxide. The overhead product is scrubbed to remove in a suitable solvent a substantial portion of or all of the remaining higher hydrocarbons, hydrogen sulphide and carbon dioxide.
