Treating a crude and natural gas stream

摘要

A process for treating a crude and natural gas stream, which at least comprises the steps of: (a) passing a crude and natural gas stream (10) through an inlet (12) into a stabilization unit (14) to provide a stabilizer content (20); (b) passing an overhead gaseous stream (30) separated from the stabilizer content (20) through a first outlet (16); and (c) passing a bottom stream (40) comprising crude liquid hydrocarbons separated from the stabilizer content (20) and free water through a second outlet (18).

1. A process for treating a crude and natural gas stream, which at least comprises the steps of:
(a) passing a crude and natural gas stream through an inlet into a stabilization unit to provide a stabilizer content; (b) passing an overhead gaseous stream separated from the stabilizer content through a first outlet of the stabilization unit; and (c) passing a bottom stream comprising crude liquid hydrocarbons separated from the stabilizer content through a second outlet of the stabilization unit; wherein the stabilization unit includes free water, wherein the free water assists in stripping of H2S from the crude and wherein the bottom temperature of the stabilization unit is less than the boiling point of free water in the stabilization unit; wherein the stabilization unit has a plurality of trays including a bottom tray; wherein the stabilization unit includes free water below the bottom tray; and wherein the bottom stream comprises some of the free water from below the bottom tray.
