Abstract
A separator for separating or partially separating oil, water, gas and solids from hydrocarbon production well fluids comprises a vessel and a cyclone contained within the vessel. An inlet passage passes through a wall of the vessel and into the cyclone, the inlet passage having means for causing the flow to rotate within the cyclone. A first outlet passage for an oil rich phase extends from a position within the cyclone and substantially on a central axis of the cyclone; a second outlet passage for a water phase extends from a base of the vessel; and a third outlet passage for the solids extends from a lower end of the cyclone.
Claims24
A separator for separating out a flow into a first fluid, a second fluid which is denser than the first fluid, and solids, the separator comprising:
- a vessel;
- a cyclone contained within the vessel;
- an inlet passage passing through a wall of the vessel and into the cyclone;
- an upper end of the cyclone being open to and in fluid communication with an interior of the vessel and defining a passage portion in fluid communication with an interior of the cyclone and with the interior of the vessel;
- a first outlet passage in fluid communication with an exterior of the vessel, wherein the first outlet passage is separate from the passage portion;
- a second outlet passage for the second fluid extending from a base of the vessel;
- and
- a third outlet passage for the solids extending from a lower end of the cyclone to the exterior of the vessel;
- wherein the third outlet passage includes a fluidizing unit situated in the cyclone.
A separator for separating out a flow into a first fluid, a second fluid which is denser than the first fluid, and solids, the separator comprising:
- a vessel;
- a cyclone contained within the vessel;
- an inlet passage passing through a wall of the vessel and into the cyclone;
- an upper end of the cyclone being open to and in fluid communication with an interior of the vessel and defining a passage portion in fluid communication with an interior of the cyclone and with the interior of the vessel;
- a first outlet passage in fluid communication with an exterior of the vessel, wherein the first outlet passage is separate from the passage portion;
- a second outlet passage for the second fluid extending from a base of the vessel;
- and
- a third outlet passage for the solids extending from a lower end of the cyclone to the exterior of the vessel;
- wherein the first outlet passage has slots which open into a part of the cyclone at which the first fluid accumulates as it separates out.
A separator for separating out a flow into a first fluid, a second fluid which is denser than the first fluid, and solids, the separator comprising:
- a vessel;
- a cyclone contained within the vessel;
- an inlet passage passing through a wall of the vessel and into the cyclone;
- an upper end of the cyclone being open to and in fluid communication with an interior of the vessel and defining a passage portion in fluid communication with an interior of the cyclone and with the interior of the vessel;
- a first outlet passage in fluid communication with an exterior of the vessel, wherein the first outlet passage is separate from the passage portion;
- a second outlet passage for the second fluid extending from a base of the vessel;
- and
- a third outlet passage for the solids extending from a lower end of the cyclone to the exterior of the vessel;
- a pipeline connected to the first outlet of the separator,
- a pump in the pipeline for increasing the pressure of flow through the first outlet, and an inductor or jet pump in the pipeline downstream of the pump, the inductor or jet pump being connected to a gas vent of the separator.
A separator for separating out a flow into a first fluid, a second fluid which is denser than the first fluid, and solids, the separator comprising:
- a vessel;
- a cyclone contained within the vessel;
- an inlet passage passing through a wall of the vessel and into the cyclone;
- an upper end of the cyclone being open to and in fluid communication with an interior of the vessel and defining a passage portion in fluid communication with an interior of the cyclone and with the interior of the vessel;
- a first outlet passage in fluid communication with an exterior of the vessel, wherein the first outlet passage is separate from the passage portion;
- a second outlet passage for the second fluid extending from a base of the vessel;
- and
- a third outlet passage for the solids extending from a lower end of the cyclone to the exterior of the vessel;
- a substantially tubular member having a proximal end and a distal end, wherein the first outlet passage is formed in the distal end of the substantially tubular member
- wherein the proximal end is arranged within the cyclone, wherein the distal end is arranged exterior to the vessel, wherein the substantially tubular member
- extends from the proximal end arranged within the cyclone,
- through the passage portion, and
- through and beyond the wall of the vessel such that the distal end including the first outlet passage is arranged exterior to the vessel.
