Abstract: A cyclone separator includes a cyclone body having an inlet and an underflow outlet. The inlet is configured to receive a mixed fluid therethrough and into the cyclone body. An underflow is separated from the mixed fluid and directed to the underflow outlet. The cyclone separator also includes an inlet insert positioned in and coupled to the inlet, the inlet insert being configured to direct the mixed fluid generally tangent to an interior surface of the cyclone body, a cyclone insert positioned at least partially within the cyclone body, the cyclone insert including a conical cyclone, and a sand collection vessel coupled to the cyclone body and in communication with the underflow outlet. The underflow is directed to within the sand collection vessel when separated from the mixed fluid in the cyclone body.

Abstract: An apparatus for removing sand from a well fluid includes a pressure vessel having an inlet and an outlet. The well fluid flows into the pressure vessel through the inlet and flows out of the pressure vessel through the outlet. A screen is positioned at least partially within the pressure vessel and configured to remove the sand from the well fluid. At least a portion of the sand that is removed from the well fluid at least partially obstructs one or more openings in the screen. A cleaning assembly is positioned at least partially between the pressure vessel and the screen and configured to remove the sand that is obstructing the one or more openings in the screen during a screen-cleaning operation.

Abstract: An apparatus for removing particles from a fluid includes a pressure vessel having an inlet and an outlet. A centrifuge is disposed in the pressure vessel. The centrifuge is configured to remove a first portion of particles from the fluid. A cyclone separator is also disposed in the pressure vessel, such that the centrifuge extends around the cyclone separator. The cyclone separator includes an array of cyclones configured to remove a second portion of particles from the fluid.

Abstract: An apparatus comprising one or more screens which in use eliminates sand and/or fluid slugs from blocking at a screen by placing at least the screen in an elevated secondary chamber, configured to prevent sand, fluid slugs and the like from accumulating around the screen.

Abstract: An assembly for adjusting a position of a vessel includes a frame for carrying the vessel, and a lifting device configured to move the frame from a horizontal position to a first vertical position by pivoting the frame, and to move the frame from the first vertical position to a second vertical position by raising the frame.
