Publication number: 20100276375Abstract: A method for treating an interface rag includes the steps of removing a volume of rag at a controlled rate from an upstream rag source and passing the rag through a high pressure pump and a heater. The heater heats the rag to a temperature of at least 350° F. to thermally decomposing any chemicals that had been added to the interface rag to promote separation. Diluent is then mixed with the heated rag to cool the rag to a temperature less than 300° F. and produce a 30 API rag. The cooled diluted rag is then treated in an electrostatic treater or sent directly to a hydrocyclone cluster. The electrostatic treater is preferably a vertical electrostatic treater with a conical-shaped lower portion and a means for agitating the solid-laden water within the treater to prevent the solids from settling on the bottom of the treater.Type: ApplicationFiled: May 1, 2009Publication date: November 4, 2010Inventor: Gary W.

Publication number: 20100108523Abstract: A vertical electrostatic coalescer comprises a first and second electrode surface and a horizontally disposed foraminous surface. The first electrode surface and horizontally disposed foraminous surface are at ground potential. The first and second electrode surfaces share the same planar orientation relative to the central longitudinal axis of the vessel. The unique arrangement of the vessel and opposing pairs of first and second electrode surfaces provides for a substantially uniform voltage field around a perimeter of the vessel and an effective voltage field for coalescence within a center of the vessel. A circular-shaped distributor pipe or a distributor housing serves to absorb momentum of the incoming emulsion stream and distribute the stream into an interior of the vessel.Type: ApplicationFiled: October 30, 2008Publication date: May 6, 2010Inventors: Gary W. Sams, William A. Summers, Sarabjit S. Randhava, Harry G. Wallace

Publication number: 20090242384Abstract: A method and system for reducing the salt content of a crude oil stream includes using a quill to disperse a water stream into the crude oil and then routing the mixed oil/water stream through a plurality of mixing stages. The water stream may include a wash water that has been preconditioned with recycled effluent water. Each mixing stage increases the homogeneity of the mixed oil/water stream. The first and third mixing stages are preferably lower pressure stages relative to the second mixing stage, which provides pressure effective for flowing the mixed oil/water stream through the third and fourth mixing stages. Upon exiting the fourth mixing stage, the mixed oil/water stream is electrostatically treated in a dual frequency separator vessel or a dual polarity separator vessel.Type: ApplicationFiled: March 25, 2009Publication date: October 1, 2009Inventors: Robert A.

Patent number: 5575896Abstract: A method and apparatus for augmenting the coalescence of water in a water-in-oil emulsion. The apparatus includes a tubular vessel having a cylindrical side wall and opposed ends. A tangential inlet in the cylindrical side wall is adjacent one of the vessel ends. A tubular electrode having an external diameter less than the internal diameter of the vessel extends concentrically within the vessel from the one end less than the entire length of the vessel. An elongated electrode extends axially and concentrically within the tubular electrode from the one end. An outlet is provided in the one end between the tubular electrode and the elongated electrode. The inlet and outlet serve to cause fluid to initially flow through the vessel in a circumferential path outside the tubular electrode and thereafter axially through the tubular electrode to the outlet. An electrical potential is applied between the electrodes and the vessel.Type: GrantFiled: January 31, 1995Date of Patent: November 19, 1996Assignee: National Tank CompanyInventors: Gary W. Sams, Floyd L. Prestridge, Merle B. Inman, Dennis K. Manning

Patent number: 5565078Abstract: A method and apparatus of augmenting the coalescence of water in a water-in-oil emulsion in which the emulsion is tangentially ejected into the interior of a cylindrically walled vessel to cause the emulsion to flow circumferentially within the vessel and to thereby cause the water component of the emulsions to migrate towards the vessel cylindrical wall, the vessel having an axially positioned electrode therein. A voltage, preferably a pulsating DC voltage, is imposed between the electrode and the vessel to thereby subject the swirling water-in-oil emulsion to an electrical potential to cause the water components to coalescence from smaller to larger droplets. The water-in-oil emulsion is passed from the vessel where the water component can be more effectively separated from the emulsion by gravitational or centrifugal separation.Type: GrantFiled: April 6, 1994Date of Patent: October 15, 1996Assignee: National Tank CompanyInventors: Gary W.
