摘要：
A process is described for separating C.sub.4 + hydrocarbons in high recovery and high purity from a feed gas comprising about 0-5% C.sub.5 and heavier hydrocarbons, 1-10% C.sub.4 hydrocarbons, 0-10% C.sub.3 hydrocarbons, 0-10% C.sub.2 hydrocarbons and the balance CH.sub.4 and light inerts. Efficient separation is effected by using a dephlegmator cycle employing only internal refrigeration.
