Abstract:
A desalter/dehydrator having a plurality of electrified coalescing stages in a single vessel, wherein the stages are isolated hydraulically to allow parallel or serial stage operations. In one embodiment, several electrical stages, each separately energized, are operated in parallel to proportionately increase vessel throughput capacity. In another embodiment, series operation is employed, wherein each successive stage receives the product from the preceding stage as feed, with fresh water being added. Placement of electrodes, distributors, collectors, etc. are determined by the type of operation to be performed in the vessel.
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:
AN INCLINED ELECTRIC TREATER FOR WATER-IN-OIL DISPERSIONS. THE TREATER INCLUDES: AN INCLINED ELONGATED CONTAINER PROVIDING A WATER ZONE AT ITS LOWER END, AN ELONGATED OIL ZONE INTERMEDIATE ITS ENDS AND A GAS ZONE AT ITS UPPER END; A WET-OIL INLET TUBE IN AND EXTENDING AXIALLY OF THE CONTAINER AND PROVIDED WITH A PORT FOR DISCHARGING WET OIL INTO THE ANNYLUS BETWEEN THE INLET TUBE AND THE CONTAINER; A FORAMINOUS CYLINDRICAL ELECTRODE IN THE ANNULUS BETWEEN THE INLET TUBE AND THE CONTAINER AND ENCIRCLING THE INLET TUBE SO THAT THERE ARE ELECTRIC FIELDS BETWEEN THE ELECTRODE AND THE INLET TUBE AS WELL AS BETWEEN THE ELECTRODE AND THE CONTAINER; AND UPPER AND LOWER ANNULAR DRY-OIL COLLECTORS INCIRCLING AND CARRIED BY THE INLET TUBE RESPECTIVELY ADJACENT THE UPPER AND LOWER ENDS OF AND WITH IN THE OIL ZONE, THE TWO COLLECTORS FACING EACH OTHER AND PROVIDING ANNULAR DRY-OIL OUTLETS BOUNDED BY AND ENCIRCLING THE INLET TUBE.
Abstract:
AN ELECTRIC TREATER WITH ELECTODES IN A HORIZONTAL TREATING COMPARTMENT ABOVE AN EMULSION-WATER INTERFACE, WITH THE EMULSION TENDING TO FLOW IN A HORIZONTAL PATH ALONG THE INTERFACE. A BAFFLE ACROSS THE INTERFACE FOR DIRECTING FLOW UP AWAY FROM THE INTERFACE ANDTHROUGH OR PAST THE ELECTRODES. A TILTED HORIZONTAL TREATER. A TREATER WITH A
D R A W I N G GAS SEPARATION ZONE, AN ELECTRIC TREATING ZONE, AND A SETTLING ZONE, WITH A BAFFLE AT THE TREATING ZONE AT THE EMULSIONWATER INTERFACE TO CONTROL EMULSION FLOW THROUGH THE TREATING ZONE.
Abstract:
The present invention relates to a method for the break-up of at least one emulsion and separation of the light and heavy phase with at least an de-emulsification rate of more than 9 % in only one apparatus (module) within less than 5 min by applying at least one time dependent or temporal changeable electrical field wherein the at least one electrical field is a high frequency (HF) singular alternating current (AC) field with an electrical field strength between 2,000 and 100,000 V/m and a frequency (HF) between 12,000 Hz and 200,000 Hz. The present invention relates furthermore to a method for the treatment of at least one emulsion by applying at least one direct current (DC) field and at least one high frequency alternating current -HF/AC field wherein the at least one DC field, in particular a pulsed DC- field, and the at least one HF/AC field are applied in series to the emulsion to be treated. The present invention refers further to a device for conducting said methods.
