ABSTRACT:
Heavy components of hydrocarbon gas mixtures are recovered through partial condensation of a first portion of the starting gas by indirect heat exchange with a refrigerant wherein the condensate formed is entrained in the gas stream. The condensate is separated from the resulting partially condensed, two-phase mixture and the separated condensate is then thermally stripped of light components by heat exchange with a second portion of the starting gas which is thereby also partially condensed. Heavy components from the starting gas mixture are recovered as stripped hydrocarbon condensate.
