摘要： A method is disclosed which comprises the steps of (a) flowing a first fluid through a pressure transfer device (29) to increase the pressure of the first fluid; (b) flowing the first fluid into a semi-permeable membrane separation element (11), wherein flowing the first fluid into the semi-permeable membrane separation element (11) changes the first fluid into a second fluid; and (c) flowing the second fluid through the pressure transfer device (29) to transfer pressure from the second fluid to the first fluid. In an RO mode, the method can be used to produce high quality water. Power can be generated from two aqueous solutions of different salt concentrations in a PRO mode.

摘要： A pressure transfer device for the transfer of pressure energy from a high pressure fluid stream to a lower pressure fluid stream wherein a generally cylindrical housing (61) contains a rotor (63) having a plurality of channels (65) extending axially therethrough that revolves about a central stator (67) or within a surrounding sleeve (73) and a pair of end covers (69, 71) which slidingly and sealingly interface with respective planar end faces (68) of the rotor. The end covers (69, 71) and the accompanying components of the device are constructed so as to allow the channels to be at least twice filled with a high pressure first liquid during each revolution of the rotor and thus discharge twice the volume of a pressurized second liquid than if they were filled only one with high pressure liquid.

摘要： A pressure exchanger for simultaneously reducing the pressure of a high pressure liquid and pressurizing a low pressure liquid. The pressure exchanger has a housing having a body portion; with end elements at opposite ends of the body portion. A rotor is in the body portion of the housing and in substantially sealing contact with the end plates. The rotor has at least one channel extending substantially longitudinally from one end of the rotor to the opposite end of the rotor with an opening at each end. The channels of the rotor are positioned in the rotor for alternate hydraulic communication with 1) high pressure liquid and 2) low pressure liquid, in order to transfer pressure between the high pressure liquid and the low pressure liquid. Because of the high pressures and the high angular velocities, this is a highly cavitation prone structure, In order to prevent cavitation, there are one or more grooves in one or both of the end plates. These grooves bleed pressure out of the channels, for example to a lower pressure channel or to a sealing volume between the end piece and the rotor.

摘要： A system and method of producing oil is provided. The system includes a support module that provides air, water and fuel to a well. A steam generator is fluidly coupled to the support module to receive the air, water and fuel. The steam generator includes an injector having a plurality of tubes. The tubes have an outer surface with an oxidation catalyst thereon. The steam generator is configured to divide the supplied air and direct a first portion through the tubes. A second portion of the supplied air is mixed with supplied fuel and directed over the outside of the tubes. The air and fuel is burned in a combustor and water is sprayed on the combustion gases to produce steam. The steam and combustion gases are directed in the direction of the oil reservoir.

摘要： A system includes a hydraulic energy transfer system configured to exchange pressures between a first fluid and a second fluid, wherein the first fluid has a pressure higher than the second fluid. The hydraulic transfer system includes a cylindrical rotor configured to rotate circumferentially about a rotational axis and having a first end face and a second end face disposed opposite each other, a first end cover having a first surface that interfaces with the first end face of the cylindrical rotor, and a hybrid hydrodynamic-hydrostatic bearing system configured to resist axial displacement of the cylindrical rotor.
