Abstract

一种与管式分离器相连的装置,包括直径大体等于或略大于分离器入口管(3)/出口管的直径的扩展管体(1)。分离的气体歧管(2)布置成与入口连接。所述歧管(2)包括多个竖直的脱气管(7),这些脱气管与分离器的入口稍前方的入口管(3)相连,并终止于上面的、优选微微倾斜的集气管(6)。气体通过竖直的脱气管向上转向并收集到集气管(6)中,以在分离器后面返回到出口管或者向前输送到气罐或气体处理设备。

Description

管式分离器入口
技术领域
本发明涉及一种管式分离器,或更确切地说涉及一种管式分离器入口 , 其包括直径大糾目当于或略大于分离器入口管/出口管的直径的扩展管体。 背景技术
本案申请人于1996年首次提交了上述类型的管式分离器的专利申请,其 中之一t^l国际专利申请号为PCT/NO 03/00265的分离器的专利申请。管式 分离器可非常有M分离含有不可混合的流体成分的流体,并且与传统的重 力分离器相比是一种简单、结构轻便的解决方案。 一方面由于设计的原因, 在分离流体(如油、气体和流气量较高的水流)的某些情况下,可肯汰生段 塞流,这会降低分离器的分离效果。本发明提供了一种可以完全消除此类段 塞流的解决方案。
发明内容
本发明的特征如附带的独立权利要求1所述。 M权利要求2-3说明了本发明的优选特征。 附图说明
参照附图在下文中通过实例对本发明进行更详细的阐述:
图1表示才娥本发明的带有入口的分离器的~^分的纵向剖视图; 图2表示才娥本发明的#^实施例的分离器的~~^分的纵向剖视图;
图3表示才M^^发明的分离器的-^P分的智一氏实施例的另一实例的纵向
剖视图。
M实施方式
如上所述,图1表示才娥本发明的带有入口的管式分离器1的1分, 该入口与供给例如油、7JC和气体的多相流的供给管3相连。
如果气^/流体成#供给管的设计不宜,则管式分离器上游的多相流中 的流动形态通常为气^/^/N^塞流。在图中,深色部分表示流g塞4,浅 色或白色表示气泡5形式的气体。
本发明包拾'刺破"气泡并去除它们,使得W目主要收集到气体收集器中
而^目保留在主管中。i^l通过与入口连接的分离的气^t管2实现。歧管2 包括多个竖直的脱气管7,这些脱气管与分离器入口稍前方的输送管相连,并 且其终止于微微倾斜的集气管6。因此气体通过竖直的脱气管向上输送,并收 集到集气管6中。
实验表明这是一种在确保向管式分离器1供应恒定流体的同时消除g ?虎的有效方法。
在分离器的后方,去除的气体经由集气管6旁过管式分离器并加入到油
相之中,或者可以向前输^J'J气^isL类似容器。本系统可以设计成使得气体
去f^t过系统中的正常压I^ii行。
图2表示另一替换解决方案,其中带有气^t管2的供给管3提升到比 管式分离器1高的位置(区域9中)。如上述旨,通过使气^Mt管升高到 管式分离器上方,气^f皮迫沿着气^径,例如上升到气M管2。
此外,如图3所示,在通向分离器的入口处,歧管的最后一个脱气管7 的下方(在8处),输送管的直径可以扩大,例如与管式分离器的直^4目同。 通过增加气M管的^部分的直径来降低管内的流体^1,未分离的气体 可以流回到最后的脱气管7中。
依据本发明的气M管的设计目的在于:
1. 用简单的方式使多相流体不受高剪切力影响M气体/油/水的井产流 体中分离出^目。高剪切力通常不利于分离。
2. 确保流体流在分离器中具有正确的相位,例如对于7M目是连续的水流, 对于油相是连续的油流。这将减少分离器入口中的》V^以及〉'^^过程中入口 中的多重M的形成。

Claims (3)
