Claim 0:
1. A system for dehydrating and desalting oil, the system comprising:
a vessel containing a crude oil inlet for introducing crude oil into an interior space of the vessel;
a fixed super-hydrophobic mesh subsystem comprising at least one fixed, unmovable super-hydrophobic mesh, the fixed super-hydrophobic mesh subsystem residing within the interior space of the vessel;
an inductor cup set system secured above the fixed super-hydrophobic mesh subsystem, the inductor cup set 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 an 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 of rotation based on the comparison of the induced voltage determined by the inductor cups, the movable super-hydrophobic mesh subsystem residing above the inductor cup set within the interior of the vessel; and
a metal grid subsystem above the movable super-hydrophobic mesh subsystem within the interior of the vessel, the metal grid subsystem comprising at least one metal grid electrically coupled to a transformer residing outside of the vessel, the metal grid to electrostatically dehydrate the crude oil during operation.
