Abstract

A system includes a vessel containing a crude oil inlet for introducing crude oil into the vessel; a fixed super-hydrophobic mesh subsystem comprising a fixed super-hydrophobic mesh; an inductor cup set system comprising at plurality of inductor cups, each of the plurality of inductor cups comprising a primary coil and a secondary coil, the inductor cups to determine an amount of water in the crude oil based on a comparison of the induced voltage between the primary coil and the secondary coil; a movable super-hydrophobic mesh subsystem comprising a super-hydrophobic mesh coupled to at least one stepper motor, the stepper motor to rotate the mesh by a predefined angle based on the comparison of the induced voltage determined by the inductor cups; and a metal grid subsystem comprising a metal grid electrically coupled to a transformer residing outside of the vessel, the metal grid to electrostatically dehydrate the crude oil.

Claims (15)

1. A method comprising:

directing crude oil into an interior chamber of a vessel of a dehydrator and desalter system;

performing a first liquid phase separation of water from the crude oil using a fixed super-hydrophobic mesh subsystem that includes at least one fixed super-hydrophobic mesh;

determining a residual water content in the crude oil using one or more inductor cup sets;

determining, based on the residual water content in the crude oil from the one or more inductor cup sets, whether to rotate a movable super-hydrophobic mesh for a second liquid phase separation of water process;

performing the second liquid phase separation of water process from the crude oil using the movable super-hydrophobic mesh;

performing a first electrostatic dehydration process on the crude oil using a first set of electrified metal grids;

performing a second electrostatic dehydration process on the crude oil using a second set of electrified metal grids; and

causing the crude oil to exit the vessel.

2. The method of claim 1 , further comprising testing the crude oil for salt content using an auto salt analyzer circuit.

3. The method of claim 2 , further comprising adding water wash to the crude oil if the salt content in the crude oil is above a threshold amount.

4. The method of claim 1 , further comprising applying an electrical bias the first set of electrified metal grids using an alternating current.

5. The method of claim 1 , further comprising applying an electrical bias the second set of electrified metal grids using a direct current.

6. The method of claim 1 , further comprising rotating the movable super-hydrophobic mesh by a predetermined angle of rotation based on an induced voltage mismatch between a primary inductor coil and a secondary inductor coil for at least one set of inductor cups.

7. The method of claim 1 , wherein performing the first liquid phase separation of water from the crude oil using a fixed super-hydrophobic mesh subsystem comprises separating water from crude oil using a plurality of fixed, unmovable super-hydrophobic meshes.
