    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: 7465376
    Abstract: The invention provides for the removal of impurities from treatment fluid including a base liquid and a variety of impurities contained in the base liquid by conveying the treatment fluid to at least one preheating separating device, including a preheating heat exchanger and a separator unit, before the admixture of a carrier gas to the treatment fluid. The treatment fluid is preheated by the preheating heat exchanger to a temperature below the boiling temperature of a base liquid so that the liquid impurities with lower boiling temperatures than the base liquid are evaporated and expelled thermally, whereby the evaporated and expelled impurities are separated in the separator unit of the preheating separator device. The treatment fluid is then evaporated and separated from impurities having a higher boiling point than the base liquid.

  • Patent number: 6695951
    Abstract: The present water reclamation system includes a series of concentric thin shells. The shells mount within a housing that can be maintained under vacuum or low pressure. The shells rotate at high velocity. Contaminated liquid from outside the housing is injected into the space between half the shells. The centrifugal force causes the liquid to form a thin film along the inward facing surface of the shell. A compressor lowers the pressure adjacent the thin film causing the liquid to boil. The compressor carries the vapor to the other side of those shells at a slightly higher temperature. There the vapor encounters the wall, which is cooler because its heat was transferred to boil the contaminated liquid. The vapor condenses, and rotation throws the condensate against the adjacent wall where it is collected. When condensing, the heat of condensation transfers to the shell for boiling the incoming contaminated liquid.

  • Patent number: 6428656
    Abstract: A water-cooled distilling apparatus for purifying or distilling raw water. The apparatus includes a boiler, cooling tray assembly, and collection vessel. In use, raw water is initially poured into the boiler which has a self-regulating screen in it. As the water beings to boil, the screen rises to float above the raw water. The height of the screen above the water automatically adjusts proportionately to the rate of boil to proportionately expose more or less surface area of the screen. A water film forms on the exposed surface area of the screen and clean steam rises therefrom into the cooling tray assembly where it is deflected into a condensing area on each level of the assembly. In each condensing area, heat is transferred from the steam into coolant water in a reservoir, causing the coolant water to evaporate from the reservoir and the steam to condense on the bottom of the surface of the reservoir. Distillate formed by the condensing steam is then collected and transferred to a collection vessel.
