Abstract
An electrostatic separator including a separator vessel having an oil collection portion at its upper end, a water collection portion at its lower end, at least one electrode generating an electric field, and an inlet through which an emulsion mixture enters the separator vessel before exposure to the electric field in the upper part of the vessel, wherein the separator vessel further comprises at least one routing blade located proximate to the at least one electrode to route coalesced water droplets downwardly and away from the electric field.
Claims14
An electrostatic separator comprising:
- a separator vessel;
- an oil collection portion at an upper end of the separator vessel;
- a water collection portion at a lower end of the separator vessel;
- at least one electrode in the separator vessel generating an electric field;
- an inlet through which an oil-water mixture enters the separator vessel before exposure to the electric field;
- and
- at least one routing blade comprising a pair of angled planar surfaces each extending from a terminal lower end thereof to an upper end thereof, wherein the upper ends of the angled planar surfaces form an apex that defines an upper end of the at least one routing blade, and the terminal lower ends of the angled planar surfaces define a terminal lower end of the at least one routing blade;
- wherein the at least one electrode extends through a channel formed by the at least one routing blade to route coalesced water droplets downwardly and away from the electric field.
5 more elements
An electrostatic separator vessel comprising:
- an oil and water mixture inlet;
- a first fluid outlet;
- a second fluid outlet positioned at an upper end of the electrostatic separator vessel, wherein the second fluid outlet comprises an oil outlet for oil of an oil and water mixture received by the oil and water mixture inlet;
- a plurality of routing blades forming channels, wherein at least one routing blade of the plurality of routing blades comprises a pair of angled planar surfaces each extending from a terminal lower end thereof to an upper end thereof, wherein the upper ends of the angled planar surfaces form an apex that defines an upper end of the at least one routing blade, and the terminal lower ends of the angled planar surfaces define a terminal lower end of the at least one routing blade;
- a plurality of electrodes disposed in the channels to generate an electric field, wherein the separator vessel comprises a longitudinal axis extending between a first end of the separator vessel and a second end of the separator vessel opposite the first end, and wherein the plurality of electrodes are positioned axially between the first fluid outlet and the second fluid outlet;
- and
- wherein the plurality of routing blades are separated by slots to redirect water coalesced by the electric field from the channels.
