Patent number: 4444229Abstract: An apparatus for increasing the solids to fluids ratio of a slurry is constructed from a chamber which has a substantially circular cross section with a high pressure slurry inlet mounted through said chamber wall with the axis of the inlet normal to a diameter of the chamber. A high pressure slurry outlet is mounted through the chamber wall with the axis normal to a chamber cross section. A low pressure outlet is mounted through the chamber wall with its axis substantially aligned with the axis of the circular cross section so that a certain portion of the fluid entering the high pressure inlet will exit the low pressure outlet. The amount is controlled by a valve inserted in the low pressure outlet. The fluid is preferably of the type which operated by reducing its diameter. Anticavitation may be provided for the chamber by passing air from the outside of the chamber into the chamber when the pressure in the chamber becomes less than the air pressure outside the chamber.Type: GrantFiled: May 18, 1981Date of Patent: April 24, 1984Assignee: Conoco Inc.Inventor: Jeffrey L.

Patent number: 4444260Abstract: A method for the treatment of oil well production streams to process oil-contaminated sand to recover oil therefrom and produce an ecologically acceptable clean sand residue. The process involves separating the production fluid from an oil well having sand entrained therein into a plurality of components, one of which comprises an oil-contaminated sand. The contaminated sand is contacted with a light oil solvent to initiate a solvating action of the oil contaminant. The resulting mixture of oil-contaminated sand and solvent is then contacted with water and the system then gravity separated into discrete sand, water and oil phases. The oil and water phases may be removed from the sand and the sand phase again contacted with water and the resulting mixture then subjected to gravity separation to produce separate sand and water phases. The water phase is then removed and the sand passed to a suitable disposal facility.Type: GrantFiled: August 17, 1981Date of Patent: April 24, 1984Assignee: Conoco Inc.Inventors: Phil A. Boyd, James E. Stolhand
