Abstract
A process for separating a feed gas stream containing methane, C components, C components, and heavier components into a volatile gas stream containing a major portion of the methane and C components and a less volatile stream containing a major portion of the C and heavier components by adjusting the temperature and pressure of the feed gas stream and charging it to a separator/absorber where the gas stream is separated into a first gas stream containing a major portion of the methane and C components with a minor content of C and heavier components and a first liquid stream containing a major portion of the C and heavier components with a lesser concentration of C and lighter components with the first liquid stream being fractionated in a deethanizer into an overhead stream and a bottoms stream with the bottoms stream containing primarily C and heavier components with the overhead stream containing primarily C and lighter components being at least partially condensed and separated into a liquid reflux stream, a second liquid stream and a vaporous stream. The second liquid stream is passed to an upper portion of the separator/absorber for use therein to absorb C and heavier components from a gas stream in the separator/absorber.
