Abstract: A process for the recovery of components of a feed gas containing methane and heavier components utilizing a demethanizer wherein at least two separation stages are provided, in which at least a portion of the liquid condensate from the first separation is partially vaporized to provide a vapor component that, when directed to a first feed point on the demethanizer, preferably functions as an enhanced reflux stream in the demethanizer. Preferably, the first separation is conducted at a higher pressure than the second separation, and both separations are preferably conducted at pressures higher than the operating pressure of the demethanizer.
