Publication number: 20090078652Abstract: A system and method are disclosed for purifying a waste fluid stream. The system includes a recirculation pump having an inlet for a recirculation stream and an outlet to expel a pressurized stream. The system includes a compressor having an inlet for an evaporation stream and an outlet for a pressurized evaporation stream. A primary heat exchanger has inlets for the pressurized stream and the pressurized evaporation stream, an internal surface area for heat transfer from the evaporation stream to the pressurized stream, and outlets for a cooled product stream and a heated pressurized stream. The heated pressurized stream is formed by heating the pressurized stream and the cooled product stream is formed by cooling the evaporation stream. The system includes an evaporation unit having an inlet for the heated pressurized stream and outlets for an evaporation stream and the recycled liquid bottoms stream.Type: ApplicationFiled: August 27, 2008Publication date: March 26, 2009Applicant: H2OIL, INC.Inventors: Larry D. Sanderson, James W. Schleiffarth, Leslie D. Merrill, Bradford M. Rohwer

Patent number: 7479231Abstract: A method and apparatus for separating mixtures of fluids having different densities. According to one aspect of the invention, a lower density fluid is separated from a higher density fluid. A mixture of the two fluids is received in a tank. A centrifugation of the mixture is induced in the tank. The lower density fluid is evacuated from the tank until the level of an interface created at least in part by the centrifugation between the higher density fluid and the lower density fluid reaches a predetermined threshold.Type: GrantFiled: May 4, 2005Date of Patent: January 20, 2009Inventor: Robert H. Bernard
