ABSTRACT:
A device for separating a fluid system, having at least two phases of different specific gravities, including a lower preceding centrifugal separator; and an upper succeeding centrifugal separator, each of said separators having an axially upwardly extended centrifuging chamber providing an upper tangential inlet through which the fluid system enters the chamber to swirl therein, a lower outlet for drawing the heavier phase from the chamber, and a tubular vortex finder through which the lighter phase exits from the chamber mounted coaxially within the upper end of the chamber having a lower end in the chamber downwardly spaced from the inlet and an upper end upwardly of the chamber, said separators being substantially axially aligned, and a substantially cylindrical conduit circumscribing the upper separator having a lower end connected to the upper end of the vortex finder of the lower separator and to the inlet of the upper separator, the inlet of the lower separator being adapted for connection to a source of the fluid system under pressure while the upper end of the vortex finder of the upper separator is subject to a substantially lower pressure whereby the fluid system enters the inlet of the lower separator and swirls downwardly in its chamber to separate the heavier phase to settle outwardly and downwardly therein and for passage of the once separated lighter phase upwardly through the vortex finder of the lower separator through the conduit and in the inlet of the upper separator to swirl downwardly in its chamber to separate any residual heavier phase in the once separated lighter phase to settle outwardly and downwardly therein and for passage of the twice separated lighter phase upwardly through the vortex finder of the upper separator.
