  • Patent number: 8951391
    Abstract: A solar distillation apparatus utilizing a substantially vertical reactor assembly is disclosed. The reactor includes a tubular outer shell, a base, a cap, and a central tension member. The annular space between the outer tube and the central tension member forms the reactor chamber. Seawater or other feed liquid enters the reactor chamber through the base plate. Reflected or direct solar energy heats the feed liquid, generating low pressure vapor. The vapor exits the reactor through the cap structure or the base. The concentrate left behind settles by gravity to the bottom region of the reactor's liquid column. Extension tubes on the feed openings allow feed liquid to enter the liquid column above the concentrate layer and avoid excessive mixing of the feed liquid and the concentrate. The concentrate exits the reactor through one or more openings in the base.

  • Patent number: 8871062
    Abstract: An apparatus and method are disclosed for controlling the thickness of a flowing, laminar fluid film. The film flow may be gravity-induced or the result of an alternative force. The fluid is deposited on an upper end of a flow surface where a relatively thick layer of the film forms. The film flows over a fluid dispersal region where the surface area is rapidly expanding, which results in rapid thinning of the film thickness. The fluid then flows over an active region where the surface area is designed to control the fluid film thickness. For example, in some applications, it may be desirable to maintain an approximately constant film thickness as the fluid flows over the active region of the surface. The geometry of the flow surface is used to obtain the desired control over the fluid film thickness. The flow surface is the outer surface of a solid with a closed upper end and a lower end that may be open or closed.

    Abstract: A compact and portable liquid concentrator includes a gas inlet, a gas exit and a flow corridor connecting the gas inlet and the gas exit, wherein the flow corridor includes a narrowed portion that accelerates the gas through the flow corridor. A liquid inlet injects liquid into the gas stream at a point prior to the narrowed portion so that the gas-liquid mixture is thoroughly mixed within the flow corridor, causing a portion of the liquid to be evaporated. A demister or fluid scrubber downstream of the narrowed portion removes entrained liquid droplets from the gas stream and re-circulates the removed liquid to the liquid inlet through a re-circulating circuit. Fresh liquid to be concentrated is also introduced into the re-circulating circuit at a rate sufficient to offset the amount of liquid evaporated in the flow corridor.

  • Patent number: 8034217
    Abstract: A liquid condensation system heats a liquid raw material under a decompressed circumstance and evaporates a volatile component from a liquid surface to condense the liquid raw material. Therefore, the liquid condensation system includes: liquid condensers, each of which condenses the liquid raw material; a vacuum pump that is in communication with the liquid condensers; and a warm water circulation system as a heating source that heats the liquid raw material in the liquid condensers. The volatile component evaporated in the liquid condensers is led to the outside of the liquid condensers through vapor lines. The condensed liquid that is not evaporated in the liquid condensers is led to the outside of the liquid condensers through condensed-liquid lines. Condensed-liquid-line adjusting valves are interposed on the condensed-liquid lines, and heaters are attached to the condensed-liquid lines. A control unit controls the heaters and the condensed-liquid-line adjusting valves.

  • Patent number: 8016977
    Abstract: Dry pond water evaporation systems and methods are used to evaporate large quantities of water from industrial waste water sources, such as water produced by oil and gas wells. Dry pond systems include a water evaporation system that emits waste water into the air as a fine spray or mist to promote evaporation. Water that falls to the ground and any initially dissolved solids are captured in a water capture depression. Water and solids are transferred from the water capture depression to a water collection pool. Water from the water collection pool is recirculated through the water evaporation system to further concentrate the total dissolved solids (TDS). When the TDS are sufficiently concentrated, they may be harvested, such as by evaporating off the water and recovering salts or minerals as a solid.

  • Patent number: 7967946
    Abstract: An improved boiler that allows distillation of ethanol from a continuous flow of a hydrous feedstock compound, which may be beer or other semi-solid substance. The internal compartment of the boiler is separated into different zones by a plurality of primary baffle plates and secondary baffle plates. The hydrous feedstock compound is heated as it passes from one zone to another zone and ethanol inside the hydrous feedstock compound vaporizes. The ethanol rich vapor is channeled through a collector column and then collected for further processing. The temperature of the hydrous feedstock compound is slightly different from one zone to another zone because of ethanol concentration changes as the hydrous feedstock compound moves from one zone to another. At the last zone, where most of ethanol is removed, the remaining hydrous feedstock compound is removed from the boiler.
