摘要： This invention provides a method for separating and enriching isotopes in an efficient and low-cost manner from a condensation-system (liquid or/and solid) material comprising two or more different isotopes by taking advantage of the sedimentation of atoms through an acceleration field by ultra-high speed rotation. A condensation-system (liquid or/and solid) material (5) comprising the two or more isotopes is placed in a sedimentation tank (for example, 2) which is then housed in a supercentrifuge. The supercentrifuge in its rotor is rotation driven by an ultra-high speed rotation power source, and an acceleration field of energy of 100000 G to 1500000 G, i.e., about 100 to 800 m/s in terms of peripheral velocity, is applied to the above condensed (liquid or/and solid) material under such a temperature that is specified by an isotope material to be enriched. In this case, a difference in centrifugal force applied is provided between the isotopes in the condensed (liquid or/and solid) material comprising the at least two isotopes. By virtue of sedimentation by taking advantage of this difference, isotope atoms within the condensed material interact, and, consequently, separation and enrichment of the isotopes can be realized in a higher efficiency than the case where gas is used, by conducting the separation and enrichment of the isotopes within the liquid material, using an effective material, and using a multistaged rotor system.

摘要： A gas separation centrifuge is provided with a housing having a top, a bottom and a plurality of joined side walls parallel to an axis and forming a predetermined regular polygon cross-sectional shape perpendicular to the axis. A rotor is mounted for coaxial rotation within the housing, including a plurality of inverted truncated pyramid plates forming the predetermined regular polygon shape at an outer periphery, and forming the predetermined regular polygon shape at an interior edge. The plurality of inverted truncated pyramid plates are stacked coaxially and are axially spaced apart to form planar channels therebetween and define an interior annular volume with openings therefrom into the planar channels. There are also openings through the outer periphery. A first plurality of stationary concentric input tubes extends into the interior annular volume. Each input tube is connectable to a source of inlet fluid and communicates with the interior annular volume at different distances along the axis terminating close to the bottom of the housing. A second plurality of stationary concentric output tubes also extends into the interior annular volume. Each output tube is connectable to a collection device and communicates with the interior annular volume at different distances along the axis close to the top of the housing. One of the plurality of input tubes is connected to a source of liquid solvent for injecting a quantity sufficient for coating the interior side walls to a thickness less than the minimum clearance distance between the exterior periphery of the rotor plates. A motor is connected for rotating the rotor at a speed sufficient to cause a maximum pressure above about 1,000 psi in the housing at the side walls. Another of the plurality of input tubes is connected to a source of a gaseous mixture. At least one of the outlet tubes has an opening at a position in the interior annular volume for withdrawing one gas of said mixture in a high state of purity.

摘要： A process for degassing a continuously flowing liquid stream is executed using an apparatus that comprises an air-tight housing, in which is mounted for rotation a centrifuge bowl of circular cross-section and having an inner surface for spreading centrifugally impelled liquid to be degassed and an annular peripheral trough for retaining centrifugally impelled degassed liquid. The liquid stream is fed into the bowl and the degassed liquid is withdrawn through a tube extending from an exit line outside the housing to an open end of elongate cross-section which is positioned within the trough of the bowl and is immersible in the degassed liquid. The pressure of the exiting degassed liquid is measured, the pressure measurement being used to regulate the flow of liquid into the bowl so as to maintain a substantially constant level of the liquid therein. Gas is withdrawn to maintain a sub-atmospheric pressure within the apparatus housing, and the flow of the degassed liquid stream is regulated so that the liquid level in the bowl remains substantially constant.

摘要： In connection with reduction of the pressure of newly produced oil, i.e. a mixture of hydrocarbon compounds, this conventionally is performed stepwise, a momentary pressure drop occurring at each stage.According to the invention it is suggested that oil is caused to flow radially inward in a chamber (12), which is formed by a rotating vessel (1) and which is only partly filled with rotating oil, whereby the pressure drop in the oil can occur relatively slowly. A free liquid surface is maintained in the chamber (12), and a certain gas pressure is maintained in the liquid free part thereof, while evaporated hydrocarbon compounds are removed through a central gas outlet (18). By means of a special inlet device (14; 3a, 40) it is prevented that the pressure in the oil, when it is on its way through the channel (15; 41) radially outward in the vessel (1) to the level, from which it is to flow radially inward, increases in the way that would happen if the oil would be allowed to flow freely in the channel and simultaneously be completely entrained in the rotation of the vessel.

The device for breaking down emulsions is in fact a centrifugal separator whose bowl has the respective chambers for the lighter and the heavier emulsion components to collect, said chambers communicating with the bowl interior space. A perforated inlet sleeve is provided coaxially with the bowl axis for admission of the emulsion being broken down to admit, while the bowl interior is filled with the coalescent matter made of the pelletized polymeric material.

摘要： 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.
