Process for recovering C4-hydrocarbons using a dephlegmator. |
| 摘要 |
<p>A process is described for separating C4 + hydrocarbons in high recovery and high purity from a feed gas comprising about 0-5% C5 and heavier hydrocarbons, 1-10% C4 hydrocarbons, 0-10% C3 hydrocarbons, 0-10% C2 hydrocarbons and the balance CH4 and light inerts. Efficient separation is effected by using a dephlegmator cycle employing only internal refrigeration.</p> |
