<p>A separator (10) for separating or partially separating oil, water, gas and solids from hydrocarbon production well fluids comprises a vessel (12) and a cyclone (14) contained within the vessel. An inlet passage (18) passes through a wall of the vessel (12) and into the cyclone (14), the inlet passage having means for causing the flow to rotate within the cyclone. A first outlet passage (22) for an oil rich phase extends from a position within the cyclone and substantially on a central axis (24) of the cyclone; a second outlet passage (32) for a water phase extends from a base of the vessel; and a third outlet passage (38) for the solids extends from a lower end of the cyclone.</p> |
