A system and method for separating bitumen from oil sands material is disclosed. The method may include mixing the oil sands material with a solvent in a mix tank then passing it through a centrifuge. The method may also include drying the clean oil sands material and recovering the vapors through a condenser unit. The system may further include passing the mixture of bitumen and solvent through a flash evaporator to produce pure bitumen or leaving it mixed with the higher API hydrocarbon condensate for the production of crude oil.

Devices and methods for producing purified water. The device includes a reverse osmosis subsystem, a dehumidification subsystem and a purified water storage tank fluidly coupled to the subsystems such that purified water produced by each can be locally stored. A vehicular platform, such as a ship, can be used to locate the device adjacent a supply of saline water and humid air. A saline water inlet, membrane and purified water outlet cooperate in the reverse osmosis subsystem to allow preferential passage of water relative to salt in a saline water supply, while the dehumidification subsystem includes a heat exchanger that extracts moisture from the ambient humid air. Purified water produced by each of the subsystems can be used as a potable water source. When used in conjunction with a ship, part or all of the reverse osmosis subsystem can be submersed to a depth sufficient to generate a hydrostatic pressure that is in turn sufficient to passively operate the reverse osmosis membrane such that additional pressurizing equipment, such as a pump, is not needed. Furthermore, the temperature of the water purified by the reverse osmosis subsystem may be low enough to be used as a condensing agent for the ambient humid air passing through the dehumidification subsystem.

A method and apparatus for separating a gas mixture which is at least partially ionized into a lighter and a heavier fraction by rapid rotation about an axis of a separating chamber by means of magnetic and electrical fields. The ionized gas mixture is enclosed in a closed static magnetic field configuration which is rotationally symmetrical about the axis of the separating chamber and the thus enclosed gas mixture is penetrated with an externally applied electric field whose field lines lie in planes containing the axis of the separating chamber and contain components which are perpendicular to the magnetic field.

1,031,141. Condensing vapours and melting ice; distillation of water. DESALINATION PLANTS (DEVELOPERS OF ZARCHIN PROCESS) Ltd. April 6, 1964 [April 29, 1963], No.14103/64. Heading B1B. An apparatus for condensing vapour and melting ice in a vacuum chamber 102 and which is particularly applicable to the production of pure water by distillation comprises a rotatable, hollow, frusto-conical ice receiver 116,a drive 124 for rotating the receiver, an inlet 156 through which ice is introduced into the chamber, an opening 102 through which vapour is supplied into contact with the ice to condense the vapour and melt the ice, and in outlet 164 for removing the condensate and the melted ice from the chamber. The receiver 116 is supported by a sleeve 126 which is carried by the drive 124 and has a plurality of T-shaped supports 128 welded thereto, the power portion of the receiver 116 also being secured to the supports. Further support members 132 are also employed. To delay the movement of ice along the inclined surface of the receiver movable and pivotal plates 180 which have a plurality of perforations therein to permit vapour to contact the ice are suspended from horizontal members 182,184 and 186. The condensate flows along the inclined surface and through apertures 119 of a ring 121 which is mounted on a frusto conical support which provides drain means for the condensate and then passes through apertures 160 in the supports 128 to the outlet 164. Air is removed from the chamber by passing through a central opening 179 in the member 122 and flowing, as shown by arrows, to outlet 174. In a desalination apparatus (Fig. 1, not shown) sea water is introduced into a low pressure chamber 20 where it flash evaporates so producing vapour and forming pure ice. The vapour then passes to a compressor 54 and is delivered radially outwardly into the condensing chamber 102 through an annular outlet 58 by means of a rotating impellor 72. The brine with ice crystals therein is delivered to a separator washer where the ice is separated and washed free of salt and fed to inlet 156 of the condensing chamber.
摘要:
A vapor collection system that can be used at an extra-terrestrial body is envisioned to collect target gaseous atoms and molecules that are floating around in a shielded environment at a pressure at or less than 1×10−5 bar. The shielded environment is defined within sidewalls and in some cases is defined within a cover. A condensation surface in the shielded environment is maintained at a temperature between 2° Kelvin and 100° Kelvin to collect the target gas that is floating around, which condenses on the condensation surface as a liquid. A collection receptacle at the condensation surface collects the liquid. A heating element in the shielded environment is made to heat and release the target gas from minerals at or beyond the rim. The gas floats around in the shielded environment.

An apparatus having a honeycomb rotor for adsorbing solvent in to-be-treated gas that is supplied to the rotor, which rotor also receives a supply of regenerating water vapor, wherein the water vapor is laden with the solvent after desorption of the solvent takes place, the water vapor mixture being then condensed. A seal structure is provided between the rotor and a housing to divide the interior of the housing into a plurality of regions, the seal allowing the rotor to rotate. The gas to be treated and reactivating water vapor are supplied to one of the regions at different positions in the direction of rotation of the rotor, whereby continuous and high speed treatment can be performed. The water vapor mixture which is not condensed, along with gases used to dry the rotor, are combined with the to-be-treated gas.

A DEVICE FOR ENABLING A LIQUID TO BE DISCHARGED FROM A ROTATING CHAMBER THROUGH AN END OPENING FORMED IN A CASING PORTION THEREOF AND FOR PREVENTING A GASEOUS FLUID FROM FLOWING THROUGH SAID OPENING IN EITHER DIRECTION, WHICH COMPRISES THE OUTER SEMITORIC HALF OF A TORIC CHANNEL WITH ONE OPENING OF THE CHANNEL DIRECTLY AND SEALINGLY CONNECTED TO SAID CASING END OPENING AND WITH THE CONVEX SURFACE OF THE CHANNEL IN A POSITION RADIALLY MORE REMOTE FROM THE ROTATIONAL AXIS OF THE CHAMBER THAN SAID OPENING, A DISC TRANSVERSE TO THE AXIS EXTENDS RADIALLY INTO THE CHAN-
NEL SO THAT, UPON LIQUID BEING DISCHARGED FROM SAID CASING END OPENING, SAID LIQUID FIRST FILLS SAID CHANNEL TO FORM A LIQUID PLUG BEFORE ISSUING AT THE OTHER END OF THE CHANNEL. IN A PREFERRED EMBODIMENT THE CASING END OPENING AND THE CHANNEL EXTEND, WIDTHWISE, CIRCUMFERENTIALLY AROUND THE ENTIRE CHAMBER.
