ABSTRACT:
A method of treating a hydrocarbon stream such as natural gas comprising at least the steps of: (a) providing a hydrocarbon feed stream (10); (b) passing the feed stream (10) through a first separation vessel (12) to provide a first gaseous stream (20) and a first liquid stream (30); (c) passing the first gaseous stream (20) from step (b) through a high pressure separation vessel (14) to provide a second gaseous stream (40) and a second liquid stream (80); (d) maintaining the pressure of the first gaseous stream (20) between step (b) and step (c) within +10 bar; (e) passing the first liquid stream (30) of step (b) through a stabilizer column (16) to provide a third gaseous stream (60) and a stabilized condensate (70); and (f) feeding the second liquid stream (80) from step (c) into the stabilizer column (16).
