  • Patent number: 9567237
    Abstract: A method for treating process distillate heavies produced during uranium fluoride purification is described. The heavies contain primarily uranium hexafluoride, UF6, and molybdenum oxytetrafluoride, MoOF4. The uranium hexafluoride is removed via distillation at reduced pressure leaving essentially MoOF4 containing <0.1% of residual uranium hexafluoride. This mixture is hydrolyzed in water, then treated with a solution of sodium hydroxide until a pH of at least 7.5 is reached. The precipitated sodium diuranate and sodium fluoride are removed by filtration. The filtrate is reacted with calcium chloride to precipitate the molybdenum values as calcium molybdate containing trace quantities of calcium fluoride.

  • Publication number: 20150129413
    Abstract: A gas separation process for treating a gas stream containing vapors of condensable components. The process includes two membrane separation steps, the second step using membranes of lower selectivity than the first step. Advantageously, the first membrane separation step may be carried out outside the pressure-ratio-limited region and the second membrane separation step may be carried out within the pressure-ratio-limited region. The second residue stream is a desired product of the process, and the process is particularly useful for applications where the target concentration of component A in this product is low, such as below 1-2 vol %.

De-oiled water is processed in an evaporation system producing a distillate that allows steam to be generated with either drum-type boilers operating at higher pressures or once-through steam generators (OTSGs) operating at higher vaporization rates. Evaporator blowdown is treated in a forced-circulation evaporator to provide a zero liquid discharge system that could recycle >98% of the deoiled water for industrial use. Exemplary embodiments of the invention provide at least one “straight sump” evaporator and at least one hybrid external mist eliminator.

    Abstract: The present invention is directed to a modular distillation system incorporating a removable capsule for containing source material for extraction. Through the action of the invention, the steam distillation process described herein produces a substantially larger amount of volatile oil than a distillation system that does not use an enclosed, modular system. The present invention provides for an apparatus that allows for greater contact between the steam and plant matter during the distillation process through the use of a closed removable capsule containing relatively small amount of plant matter. Additionally, the present invention is directed to a system that allows the generation of higher quality distillate and considerably higher quantity of volatile oil extracts by forcing the steam to evenly disperse through a removable capsule, and by preventing the condensed liquid to return back to the boiling water within the vessel.

    Abstract: Produced natural gas containing carbon dioxide is dehydrated and chilled to liquefy the carbon dioxide and then fractionated to produce a waste stream of liquid carbon dioxide and hydrogen sulfide. Natural gas liquids may be first separated and removed before fractionation. After fractionation, the waste stream is pressurized and transmitted to a remote injection well for injection either for disposal of the waste stream and preferably to urge hydrocarbons toward the producing well. A hydrocarbon stream proceeds from fractionation to a methanol absorber system which removes carbon dioxide gas. The hydrocarbon stream is thereafter separated into at least hydrocarbon gas, nitrogen and helium. Some of the nitrogen is reintroduced into a fractionation tower to enhance the recovery of hydrocarbons. A methanol recovery system is provided to recover and reuse the methanol. The hydrocarbons are sold as natural gas and the helium is recovered and sold. Excess nitrogen is vented.

  • Patent number: 8460509
    Abstract: A fluid evaporation system includes a housing bounding a fluid reservoir and an air flow path that is disposed over top of the fluid reservoir. The housing has an inlet opening and a spaced apart outlet opening that both provide communication between the outside environment and the air flow path. A fan is positioned to draw the air out of the air flow path through the outlet opening. A baffle projects into the air flow path at a location between inlet opening and the outlet opening so as to constrict the area of the air flow path thereat. A plurality of spray nozzles are positioned within air flow path between the baffle and the first end of the housing. A pump is configured to draw fluid from the reservoir and deliver it to the plurality of spray nozzles.

  • Publication number: 20130118890
    Abstract: The invention can be used to improve the yield of degraded heat transfer oil (1) recovered from a solar thermal facility, comprising the successive separation of heavy components (4) (ortho-, meta- and para-terphenyl) and light components (7) (phenol and benzene). The plant comprises: an air-cooled cooler (2) which cools the degraded heat transfer oil (1) to obtain a cooled oil (12); a distillation column (3) which separates the heavy components (4) and a vapour (15) of light components (7) plus oil from the cooled heat transfer oil (12); and a rectifier (6) which separates the light components (7) and the regenerated oil (17) from the vapour (15). The method comprises the cooling of the degenerated heat transfer oil (1) in the air-cooled cooler (2), the separation of the heavy components (4) in the distillation column (3), and the separation of the light components (7) and the regenerated oil (17) in the rectifier (6).

  • Patent number: 8425734
    Abstract: A system and process that are a hybrid of distillation and membrane separations offers a highly efficient means of separating a fluid feed mixture into organic, solid, and aqueous components. The distillation section is followed by two membrane separation sections operated in parallel, with the distillation section separating the feed mixture into an organics-rich fraction and an organics-depleted and solids-rich fraction. One membrane section operates on the organics-rich fraction and separates it into a more organics-rich sub-fraction and a water-rich, organics-depleted sub-fraction, while the other membrane section operates on the organics-depleted, solids-rich fraction from the distillation section and separates it into a solids-rich sub-fraction and a solids-depleted, water-rich sub-fraction.

  • Patent number: 8349185
    Abstract: The invention pertains to a method for rebalancing a solvent solution useful for treating photosensitive printing elements having a photopolymerizable layer. The solvent solution becomes contaminated with unpolymerized material and other materials that release from the photosensitive printing elements during washout treating, and separation of contaminates also removes some of one or more components in the used solvent solution. The method rebalances the proportion of the components in a solvent solution having 3 or more components. The method includes measuring a reclaimant, which has been separated from the contaminates, for two or more properties, calculating a mass of the components to be added to the reclaimant based on an equation generated for each measured property, and adding the mass of the component or components to the reclaimant to adjust the proportion of the components in the reclaimant to targeted proportions.

  • Patent number: 8323500
    Abstract: A process for removing water from solid material using liquid-solid extraction and liquid-liquid extraction. In most embodiments, multiple solvents are used to step-wise remove the water from the solids and obtain dry solids. Multiple solvents facilitate the removal of the water from the solids, by step-wise replacing the water with a solvent, replacing that solvent with a different solvent, and then eventually removing the second solvent from the solids. The process utilizes a lesser amount of thermal energy to dry the solids and separate the solvents than conventionally used in drying processes. The first solvent selected has a lower heat of vaporization, enthalphy of vaporization, boiling point, or other such physical property, than water. Each subsequent solvent has a still lower heat of vaporization, enthalphy of vaporization, boiling point, or other such physical property then its predecessor.
