Description

管式分离器
本发明涉及一种用于分离流体的管式分离器，特别是用于分离带有例如油、气和水这样的不相溶的流体组分的流体，包括延伸的管式分离器主体，其直径大体等于或略大于分离器的入口管和出口管的直径。
上述类型的管式分离器的专利申请在1996年由本申请人首次提交。这些专利申请之一是申请人自己的国际专利申请PCT/NO03/00265，其展示了这种分离器。管式分离器对于具有不相溶流体组分的流体的分离是非常有效的，并且与传统的重力分离器相比，显示了一种简单、结构轻的解决方案。这种现有技术的分离器被设计为延伸的、大体是直的管体，其中连接于分离器的入口和出口管与分离器主体基本在一条直线上。然而，计算和试验显示，即使流体的流量相当高，分离器主体也不必然需要是直的。它可以被设计成弯曲的路径而丝毫不影响分离器的分离能力或分离效能。将管式分离器设计为具有弯曲的路径或路线的优点在于：分离器可以制造得更加紧凑，而且适合于设计的其要安装的位置或结构。因此，这种分离器的价格也可能降低相当多。
本发明的特征在于：从入口到出口，分离器主体在其纵向设计的一个或多个部分具有弯曲的路径或路线，正如所附的独立权利要求1限定的。权利要求2-6指出了本发明的有利特征。
通过实施例，并参考附图，下面将对本发明进行更详细的描述，其中：
图1显示了传统设计的管式分离器图。
图2显示了根据本发明的管式分离器图，其具有U形回路形式的弯曲路径或路线。
图3和图4显示了根据本发明的管式分离器的图例，它们具有不同的弯曲路径或路线。
如上所述，图1显示了传统设计的管式分离器图，也就是形式为：延伸的直的主体1；设置在主体1一端的入口2，其与输送管3相连以供应将被分离的流体，例如油/水；以及每个分离的流体组分的出口4、5。
图2显示了根据本发明的管式分离器，在此处显示的例子中，其设置为与水下油和/或气的生产井5的底盘(template)相连。装置6和7(扩孔器的发送器和接收器)也设置为与分离器相连以清洁分离器。在此处显示的例子中，分离器主体1本身被设计为U形路线。来自井5的流体通过输送管3被输送到分离器1。由于分离器主体被设置为U形回路，分离器也可以很容易的被扩孔器或清管器清洁，扩孔器或清管器从清管器发送器6传送到清管器接收器7。这种解决方案得到了紧凑而且也容易清洁的管式分离器。
有利的是，U形管回路中的分离器主体1的曲率半径R可以不小于弯曲管体的临界半径，即弯曲操作(生产操作)中避免管体变形(压缩)的最小半径。这可以根据材料和壁厚的不同而有些变化。然而，作为经验法则，对于钢材，半径R不应大于管体半径的3倍，即R＞3r。有利的是，半径R应当更大一些，例如R＞5r。
图3显示了根据本发明的管式分离器的另一个例子。该解决方案与图2大体相同，但是分离器主体为螺旋回路以增加长度并从而提高分离器主体的效能。在此处显示的例子中，回路中管体的高度可以变化，有利的是，入口应当在出口上方，并且三相分离器从入口到出口的管体的下降应当不超过-0.5度(负的半度)，油/水分离器从入口到出口的管体的下降应当不超过-3度(负的3度)，以防止分离器中的流体流量超过产生紊流的预期流量而导致非层流。除了前面例子中显示的部件外，此处显示的例子的解决方案显示了用于返回或进一步输送水的泵12和水力旋流器11。
图4显示了根据本发明的分离器的第三个例子，其中分离器主体适于水下底盘的框架。在该例子中，管体1沿框架结构10侧部延伸，以使底盘上的空间有效利用。可替代地，管体1本身可以有利地构成框架结构的集成部分，并从而构成其支撑部分。
请注意，如权利要求限定的，本发明并不限于上面所示的实施例和描述，其中分离器的设置基于底盘。因此，指定设计的管式分离器可以用于需要分离流体的任何环境，例如平台上、船上，或陆地上、建筑物内或野外的任何处理厂。
