Patent number: 10654727Abstract: A method and system for de-oiling a feed comprising oil and water. The feed has an input temperature above the boiling point of water and an input pressure sufficient to maintain the water in a liquid state. In at least one embodiment, the method comprises pumping the feed with a motive pump through a phase separator having a restriction to effect a phase separation of oil and water in the feed and produce an agitated mixture, supplying the agitated mixture from the phase separator into a pressure vessel operating at a pressure sufficient to maintain in a liquid state water that is at a temperature above the boiling point of water, removing an oil phase from the pressure vessel, and removing a water phase from the pressure vessel.Type: GrantFiled: February 19, 2019Date of Patent: May 19, 2020Assignee: 1501367 Alberta Ltd.Inventor: Wade R. Bozak

Patent number: 9334175Abstract: A method of fluid treatment of a feed comprising oil and water, the method comprising: supplying the feed into a flotation cell, the feed having an oil concentration, the flotation cell containing a working fluid and the working fluid having a surface; removing an oil phase from the surface of the working fluid; removing fluid from the flotation cell through one or more outlets below a working fluid level in the flotation cell; and controlling flow through the one or more outlets to maintain the working fluid level in the flotation cell within a predetermined range independent of variations in the oil concentration of the feed. A related apparatus is also disclosed.Type: GrantFiled: June 30, 2011Date of Patent: May 10, 2016Assignee: 1501367 Alberta Ltd.Inventor: Wade R. Bozak

Publication number: 20120298587Abstract: A fluid treatment device and method is proposed for the treatment of a fluid that has components to be separated, such as tailings. The fluid treatment device in one embodiment comprises a motive pump connected to drive fluid to be treated along a conduit through a restriction forming a nozzle into a mixing chamber and thence to a discharge. A port, which may be controlled by a valve, admits gas into an initial portion of the mixing chamber. The motive pump, nozzle, gas port and mixing chamber together form a phase separator. Multiple phase separators may be connected together in series. The mixing chamber may have constant diameter and a length to diameter ratio of 20:1 or 60:1 or more. The conduit terminates in a discharge. The discharge may supply the treated fluid to a secondary separation device such as a flotation cell. Solids and liquids may be taken off the flotation cell for disposal, further processing or delivery into a sales line.Type: ApplicationFiled: January 11, 2011Publication date: November 29, 2012Applicant: RJ OIL SANDS INC.Inventor: Wade R.

Patent number: 6527960Abstract: A process for separating oily films from sand particles carried in a solvent free water stream includes the use of a jet pump scrubber in a density classification tank to treat such oily coated particles at controlled operating temperatures above 65° C. whereby, at such controlled temperature, enhanced cavitation in the jet pump separates the oily film from the sand particles to form slop oil, the tank providing for recirculation of the particles through the jet pump before discharge.Type: GrantFiled: August 17, 2000Date of Patent: March 4, 2003Assignee: Canadian Environmental Equipment & Engineering Technologies, Inc.Inventors: Diana L. Bacon, Patrick J. Cochrane, Wade R Bozak, Roderick M. Facey
