"PROCESS FOR SEPARATION OF C2+ OR C3+ OR C4 HYDROCARBONS FROM A GAS MIXTURE" Abstract In a process for separation of C2+, C3+ or C4 hydrocarbons by cooling and partial condensation from a gas mixture also containing, besides these components, lighter components, one improvement comprises first precooling the gas mixture to the extent that a portion of the hydrocarbons to be separated condenses, feeding the partially condensed gas mixture into the lower section of a separation column, removing a gaseous fraction from the upper section of the separation column, further cooling and partially condensing the gaseous fraction in a heat exchanger, and feeding the condensate as reflux to the head of the separation column.
