Abstract

What is proposed is a method for an efficient processing of associated petroleum gas and natural gas having an increased content of methane homologues, inter alia, gases from the second and third stages of oil separation having close to atmospheric pressure, thus producing cleaned "dry gas" and a number of valuable liquid products. During the first stage the gas with an increased content of heavy methane homologues is undergoing a) partial oxidation, thus producing ethylene and CO; and/or b) partial oxidation, thus producing methanol and CO. During the second stage the gas is subjected to carbonylation.
