Abstract: A separator for oil-continuous dispersions containing a dispersed water phase. A horizontal vessel contains a horizontal non-pressure baffle forming an outlet zone superimposed above an electric field treatment zone. Openings along one side of the baffle provide fluid communication between these zones. An open-bottom inlet zone, extending longitudinally along the other side of the vessel, is formed by a vertical non-pressure baffle extending downwardlly from the horizontal baffle to adjacent the bottom of the vessel. A water separation zone extends upwardly to a horizon intermediate the open bottom of the inlet zone and the horizontal baffle to define the electrical field treatment zone. Passageways in the vertical baffle deliver dispersion from the inlet zone into the electric field treatment zone with volumes of bulk water phase being discharged downwardlly through the open bottom of the inlet zone into the water separation zone. Electric field resolution produces a dry oil phase passing into the outlet zone for removal from the vessel. Accumulating water phase is removed through an outlet from the water separation zone.

Abstract: ALREADY-TO-USE LEAD SULFIDE CATALYST FOR USE IN THE BENDER (A REGISTERED TRADEMARK) SWEETENING PROCESS OF SOUR PETROLEUM PRODUCTS. THE LEAD SULFIDE CATALYST COMPRISES A CARRIER OF PARTICULATE INERT SOLIDS AND A RELATIVELY DRY EXPOSED COATING RESIDING ABOUT THE EXTERIOR SURFACE OF THE SOLIDS THE COATING IS FORMED OF A MIXTURE OF SODIUM SULFIDE AND LEAD OXIDE REACTED IN THE PRESENCE OF AN AQUEOUS SOLUTION OF SODIUM SILICATE BINDER, PREFERABLY THE SODIUM SULFIDE IS INTRODUCED IN A STOICHIOMETRIC AMOUNT RELATIVE TO THE LEAD OXIDE IN THE MIXTURE. THE CATALYST CAN BE PROTECTED FROM OXIDIZING GASES OR MOISTURE BY A HYDROCARBON SOLUBLE COVERING ENCLOSING THE COATING ON THE CARRIER. FOR EXAMPLE THE COATING MAY BE A HIGH-MELTING POINT NATURAL, PETROLEUM OR SYNTHETIC WAX.

Abstract: An electrical treater for resolving water-in-oil dispersions in a first enclosure positioned above a second enclosure in a shipboard mounting. The first enclosure contains dispersion inlet means, oil phase removing means and a coalescing section containing an electrical field to effect separation of the dispersion into continuous oil and water phases. An upright passageway transfers the water phase from the first enclosure to the second enclosure into a water accumulator with a body accumulated water being maintained below the upright passageway. Flow control means associated with the upright passageway provide for relatively unobstructed downward flow and restricted upward flow of the water phase between the first and second enclosures.
