Patent number: 8210506Abstract: The invention is a heat exchanger that transfers heat directly between fluids which are in direct contact with each other rather than being separated by a heat conductive wall. Gas and liquid exchange heat when the gas is moved into and through a mixing chamber, and is directed to form a high speed, forced vortex gas flow. The liquid is sprayed into the mixing chamber to form droplets traveling with and mixing with the vortex gas flow. As the gas and liquid droplets move through the mixing chamber together in the vortex flow, they exchange thermal energy by direct contact. The mixing chamber length is designed so that the gas and the liquid droplets approach thermal equilibrium as the gas-liquid mixture moves into a separation chamber. Within the separation chamber, the centrifugal force of the continuing vortex movement of the gas stream separates the liquid from the gas stream and forms a layer of liquid on the separation chamber wall.Type: GrantFiled: November 19, 2009Date of Patent: July 3, 2012Assignee: Advanced Cooling Technologies, Inc.Inventor: Michael C.

Patent number: 7785400Abstract: An apparatus for separating natural gas from production streams comprising a liquid dispersion of water, sand, and natural gas is provided for. The separator comprises a vessel having an interior surface defining a spherical interior space. The interior space allows a production stream introduced therein to experience a velocity drop sufficient to allow separation of the natural gas from the sand and water components. The separator also comprises a stream inlet port in the vessel, a liquid drain in the lower end of the vessel, and a gas outlet port at the upper end of the vessel remote from the stream inlet port. A baffle is mounted in the interior of the vessel in the path of the production stream between the stream inlet port and the gas outlet port. The baffle is effective to spread and direct a high pressure production stream introduced into the interior space via the stream inlet port downward toward the liquid drain.Type: GrantFiled: June 30, 2009Date of Patent: August 31, 2010Assignee: Sand Separators LLCInventors: Emmett Ronald Worley, Shirley Royce Green

Patent number: 7780753Abstract: A dust collector cup working in the principle of fall centrifugal separation, consists of cup body (13), outlet (3) on the cup body (13), inlet (1) tangential to the circumferential wall of the cup body (13), and a separator settled in the cup body (13). The separator is composed of outlet tube (9), inlet (6) on the wall of the outlet tube (9), and the isolating shield (7) under the inlet (6) of the outlet tube (9), with the outlet tube (9) linked to the outlet (3) of the cup body (13). The fall between the horizontal positions of the lower end of inlet of the cup body (13) and the upper end of the inlet (6) of the outlet tube (9) is 0-140 mm.Type: GrantFiled: January 4, 2006Date of Patent: August 24, 2010Inventor: Weiguo Lang

Patent number: 7766989Abstract: A separator assembly for removing material that is entrained in a gas stream. The separator assembly comprises a housing having a head part which provides the upper end of the housing and a body part which provides the lower end of the housing. The separator assembly also comprises a shield which extends across the housing towards the lower end thereof so as to leave a collection space between it and the lower end in which material that is separated from the gas stream can collect. There is at least one opening in or around the shield through which the material can flow past the shield into the collection space. The separator assembly further comprises a liner sleeve which covers at least a part of the inside wall of the body part between the shield and the upper end of the body part.Type: GrantFiled: January 11, 2008Date of Patent: August 3, 2010Assignee: Parker Hannifin LimitedInventors: Brian Lane, Stephen Bittle, Ray Trowsdale
