Description

用于分离多相流体的装置
本发明涉及一种与用于分离多相流体的分离器相联的装置，它包括优选是柱形的容器，该容器有进口、用于具有较大重力的液体(例如水)的第一出口、用于具有较小重力的液体(例如油)的第二出口以及用于气体的第三出口。
现有技术有上述类型的重力分离器用于分离流体例如油、水和气体，该重力分离器是用于在平台和生产船上或在海床上的处理设备中的部件。不过，根据它们的容量，这些分离器较大和较重，需要大量空间。
现有技术还有称为管分离器的新型分离器，它由本申请的申请人开发，并基于通过可分离流体在管中的层流流动而在管中进行分离。这种分离器非常有效，需要的空间较小，并能够用于较大深度的海洋中。EP0977621表示和介绍了这种分离器。
本发明提出了一种分离器方案，它基于上述两种分离器原理的组合，其中，使得要分离的液体能够更有效地分离。
本发明的特征在于管分离器与容器的进口连接。管分离器构成要分离流体的供给管的连续部分，并与容器连接或局部伸入该容器内。
本发明涉及一种与用于分离多相流体的分离器相联的装置，包括容器，该容器有进口、用于具有较大比重的液体的第一出口、用于具有较小比重的液体的第二出口以及用于气体的第三出口，管分离器与容器的进口连接，因此，管分离器构成要分离的流体的供给管的连续部分，并与容器连接或局部伸入该容器内。
通过在容器中进一步分离之前在管分离器中首先部分分离进入的流体，可以优化分离处理，从而获得更好的性能，并减小了所需的分离器容积。
优选地，流体包括油、水和气体，对于水的连续流入流，进口布置在容器中的一高度处，该高度等于预计的水相在容器中的高度。
优选地，流体包括油、水和气体，对于油的连续流入流，进口布置在容器中的一高度处，该高度等于预计的油相在容器中的高度。
下面将通过实例并参考附图更详细地介绍本发明，附图表示了本发明的原理图。
如图所示，本发明包括普通重力分离器1，该重力分离器1包括优选是柱形的容器，该容器有进口2、用于具有较大重力的液体(例如水)的第一出口3、用于具有较小重力的液体(例如油)的第二出口4以及用于气体的第三出口5。
优选是，在容器1的端部布置隔板8。它朝着容器的上端延伸，并形成用于具有较小重力的液体(油)的门槛，以便使该液体流过并流向在容器1右侧的腔室9，第二出口4布置在该腔室9中。
本发明方案的特定特征是管分离器6与普通重力分离器1的进口2连接。管分离器6构成用于要分离的流体的供给管7的连续部分，并局部伸入重力分离器1中。管分离器6的直径大于供给管7的直径，并且大到足以获得层流。管分离器主要水平布置，这也是层流的一个条件。水平度要求取决于流动速度，即流速越快，需要越高水平度。而且，管分离器的水平度要求还将取决于流体流为两相还是三相。三相流体流将需要管分离器6有更高水平度。
图中所示的方案是用于油、水和可能的气体的分离器(即三相分离器)，具有水的连续流入流。由于水的连续流入流，优选是进口2布置成使得管分离器6的出口在这样的高度伸入普通散热器(radiator)1中，即该高度为流体在分离器的水层(水相)中达到该分离器内所需。相反，对于油的连续流入流，优选是进口将布置成使得流入流进入分离器1的油相中。
流入管分离器6中的两个液相(油/水)将在它们流过管分离器6时逐渐分离，这样，油/水层将逐渐形成有平均的液滴尺寸，如果没有使用管分离器，该尺寸将在普通分离器1的进口处大得多。这导致在普通管分离器中更快的进一步分离，且该普通分离器能够制得小得多。
气体的分离将比油/水的分离快得多，因为气体的重力比两个液体小得多。这意味着气体/气泡在到达容器1时将快速升高至液体表面，并因此构成在容器中在液体表面顶部的气相，并将通过气体出口5而向外输送。
当预计有较高气体/液体比时，脉冲阻尼进口装置优选是将布置在普通分离器中，例如开口螺纹壳体进口，如本申请人的欧洲专利申请No.1069957中所述。这时，进口2也将位于比分离器中的液相更高的高度处。
在管分离器6和普通分离器1之间的过渡将设计成在流体流中产生最小的剪切力。这通过使用具有最小弯曲半径(优选是根本没有)的光滑管来实现。
优选是，管分离器的进口可以装配有阻尼多相流入流的输入脉冲的装置(未示出)。
本发明并不局限于附图中所示和上面所述的实例，而是由本申请的权利要求来确定。因此，本发明可以用于分离除了油、气体和水之外的流体。
