OSTI ID:5874690
A process for separating substantially all of the C/sub 3/ and heavier components and a major portion of the C/sub 2/ component from a natural gas stream using a cryogenic process. The process uses a rectifying column in combination with a fractionating column to separate the C/sub 2/ and heavier components with the reflux for the rectifying column being supplied by compressing a small portion of the overheads and condensing it via heat exchange with the overheads stream.
