    • A method for controlling a subsea cyclone separator (5) in a subsea processing system for subsea separation is described. The cyclone separator (5) is adapted to separate hydrocarbons from water. This comprises directing a predominantly water containing fluid into the inlet (4) of the cyclone separator (5), extracting a flow containing the substantial part of the hydrocarbons from an overflow (6) of the cyclone separator (5) and mainly water from an underflow (7) of the cyclone separator (5). The overflow (6) and the underflow (7) are individually pressurized by pumps (8, 9), the ratio of the pump rates of the pumps (8, 9) determining the flow-split of the cyclone separator (5). The individually pressurizing pumps (8, 9) are powered by a common motor (10) and the ratio of the pump rates is set to correspond with a target pressure ratio corresponding to target flow-split of the cyclone separator (5).
    • 描述了一种用于在用于海底分离的海底处理系统中控制海底旋风分离器(5)的方法。 旋风分离器(5)适于将烃与水分离。 这包括将主要含水的流体引导到旋风分离器(5)的入口(4)中,从旋风分离器(5)的溢流(6)中提取含有大部分烃的流,主要从 旋风分离器(5)的下溢(7)。 溢流(6)和下溢(7)由泵(8,9)单独加压,泵(8,9)的泵速决定旋风分离器(5)的分流。 单独的加压泵(8,9)由公共电动机(10)供电,并且泵速比被设定为对应于对应于旋风分离器(5)的目标分流的目标压力比。
