Zusammenfassung:1,149,975. Cold separation of gas mixtures. BADISCHE ANILIN- & SODA-FABRIK A.G. 30 Aug., 1966 [31 Aug., 1965], No. 38593/66. Heading F4P. Ethylene and acetylene are together separated from a gas mixture containing relatively low boiling point components e.g. hydrogen, carbon monoxide and methane by cooling the feed mixture which has previously been freed from hydrogen sulphide and unsaturated C 3 to C 5 hydrocarbons to within a temperature range of -104‹ to -138‹ C. thereby condensing the ethylene and acetylene which is then withdrawn as product. The cooling is effected by indirect heat exchange with work-expanded residual gas.
