FIELD: adsorption drying and cleaning of hydrocarbon gases. SUBSTANCE: proposed method of cleaning ethane fraction from sulfuric compounds and carbon dioxide includes adsorption with zeolite under pressure followed by regeneration and cooling of zeolite by means of regeneration and cooling gas; methane fraction is used as regeneration and cooling gas and zeolite CaA is used for performing this method; regeneration of zeolite is performed at temperature of 210-230 C and pressure which is below adsorption pressure by 1-2 kg/sq cm; saturated gas for regeneration of zeolite is fed to suction end of compressor of commercial gas main. EFFECT: enhanced efficiency of drying and cleaning ethane fraction due to increased duration of adsorption and effective life of zeolite. 1 dwg
