Abstract
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.
