摘要:
The present invention relates to a method of treating a hydrocarbon stream such as a natural gas stream, the method at least comprising the steps of: (a) supplying a partially condensed feed stream (10) to a first gas/liquid separator (2), the feed stream (10) having a pressure > 50 bar; (b) separating the feed stream (10) in the first gas/liquid separator (2) into a first vaporous stream (20) and a first liquid stream (70); (c) expanding the first vaporous stream (20), thereby obtaining an at least partially condensed first vaporous stream (30); (d) supplying the at least partially condensed first vaporous stream (30) to a second gas/liquid separator (4); (e) separating the stream (30) as supplied in step (d) in the second gas/liquid separator (4) into a second vaporous stream (60) and a second liquid stream (40); (f) increasing the pressure of the second liquid stream (40) to a pressure of at least 50 bar, thereby obtaining a pressurized second liquid stream (50); and (g) returning the pressurized second liquid stream (50) to the first gas/liquid separator (2).
摘要(中):
本发明涉及处理烃流如天然气流的方法,所述方法至少包括以下步骤:(a)将部分冷凝的进料流(10)供应至第一气/液分离器(2) ,进料流(10)具有> 50巴的压力; (b)将第一气/液分离器(2)中的进料流(10)分离成第一蒸气流(20)和第一液流(70); (c)使第一蒸气流(20)膨胀,从而获得至少部分冷凝的第一蒸气流(30); (d)将至少部分冷凝的第一蒸气流(30)供应至第二气/液分离器(4); (e)将在第二气/液分离器(4)中的步骤(d)中供应的物流(30)分离成第二蒸气流(60)和第二液流(40); (f)将第二液体流(40)的压力增加到至少50巴的压力,由此获得加压的第二液体流(50); 和(g)将加压的第二液体流(50)返回到第一气体/液体分离器(2)。
