  • Patent number: 9567732
    Abstract: The present invention is a device that can obtain fresh water from the moisture air and generate electricity in the process. The water collecting device comprises a vertical shaft, windmill elements for producing rotational force from wind, a vertical shaft, a water collecting tank secured at the bottom of this rotating structure, a small holed mesh with U shaped collecting ducts in the windmill structure and a generator coupled to the shaft. When the windmill structure rotates from the wind, moisture from the air adhere to the mesh and then are channeled to the water-collecting vessel through channels along the windmill frame. Additionally a generator coupled to the windmill frame produces electricity.

  • Patent number: 9249553
    Abstract: The system makes it possible to control and treat gas emanations inside a wastewater access shaft. The system includes a cover with at least one pivoting part, which is normally closed, having a substantially horizontal rotation axis and able to allow solid and/or liquid matter falling onto the main upper surface of the cover to pass toward the bottom of the access shaft. The cover also includes a raised part that has at least one lateral wall and includes a plurality of orifices situated vertically above the main upper surface of the cover. The orifices define an outlet of a gas-emanations circuit formed between the underside and the top of the cover. An air filter is arranged across the circuit. The filter is moistened by a liquid that comes from a reservoir in order to treat the emanations.

  • Patent number: 9044693
    Abstract: An accelerated vapor recompression apparatus 10 converts incoming flow 35a to a concentrate 35c by developing a concentration profile 146 within a tank 30 holding a liquid 23 containing dissolved solids. The resulting curve 160 of saturation temperature of the stratified liquid 23 (such as a brine 23 or other material 23) moves away from the curve 162 corresponding to fully mixed conditions. The shift 174, 180 in saturation temperature results in increased boiling without increased energy from a heater 70 or compressor 50. A method 90, 200 of control of the system provides interventions 203, 204, 205, 206 at different levels 92, 94, 96, 98 of control, ranging from mass flows 35 to work of a compressor 50, heat from a heater 70, and a predictive processing 215 of feedback 217 for controlling commands 216 algorithmically.

    Abstract: The device and method are provided to increase anhydrosugars yield during pyrolysis of biomass. This increase is achieved by injection of a liquid or gas into the vapor stream of any pyrolysis reactor prior to the reactor condensers. A second feature of our technology is the utilization of sonication, microwave excitation, or shear mixing of the biomass to increase the acid catalyst rate for demineralization or removal of hemicellulose prior to pyrolysis. The increased reactivity of these treatments reduces reaction time as well as the required amount of catalyst to less than half of that otherwise required. A fractional condensation system employed by our pyrolysis reactor is another feature of our technology. This system condenses bio-oil pyrolysis vapors to various desired fractions by differential temperature manipulation of individual condensers comprising a condenser chain.

Such methods provide improved volumetric productivity for the fermentation and allow recovery of the alcohol. Such methods also allow for reduced energy use in the production and drying of spent fermentation broth due to increased effective concentration of the alcohol product by the simultaneous fermentation and recovery process which increases the quantity of alcohol produced and recovered per quantity of fermentation broth dried. Thus, the invention allows for production and recovery of C3-C6 alcohols at low capital and reduced operating costs.

The apparatus comprises a wave tank and a condensation tank, the wave tank and condensation tank being connected by two pipes, each with a one-way valve, that produced a cycle of water saturated air from the wave tank to the condensation tank with a return of relatively desaturated air back to the wave tank following condensation of water. The wave tank captures the up and down motion of the waves and converts it to a pumping action. Air inside the wave tank is compressed when a wave comes in and has a negative pressure when the wave recedes. A saline water spray is introduced during wave troughs. Water evaporates into the negative pressure air hydrating the air. When the next wave comes in the water level rises inside the wave tank pressurizing the air.

  • Publication number: 20140190902
    Abstract: Waste water from an industrial process, including an organic acid, is reprocessed by introducing the waste water into a heat exchange process in which a heat exchange medium is used so that the waste water which is to be treated is heated to a temperature between 60° C. and the boiling point of the waste water. Subsequently, the waste water is partially evaporated and re-condensed, with the waste water irradiated with UV radiation during the evaporation and condensation process in the liquid and/or gas phase. As a result, a chemical transformation of the organic acid in H2O and carbon dioxide is at least partially carried out. Then, the condensed part of the purified waste water is fed back into the industrial process.

  • Publication number: 20140166468
    Abstract: The invention describes a new and simple method of construction of a stationary distillation unit and of a small portable distillation unit. The evaporation pans are made of simple materials and are covered with a transparent film. Additionally in the small portable unit its evaporation pan has a double bottom, which receives hot water. By connection of the evaporation pan with the solar collectors (12) its productive ability significantly increases. The portable and stationary desalination units of the invention use solar power exclusively and simultaneously produce two products: distilled water and salt. The exploitation of solar radiation occurs both in the part of the unit covered by the transparent film as well as in the use of hot water produced by the solar collector connected to it, thus speeding up the evaporation of sea water.

  • Publication number: 20140138236
    Abstract: An atmospheric water generator and system for condensing and collecting moisture contained in the air serves to cool and dehumidify the air. One aspect of the design includes generation of electricity via a turbine configured to be actuated by an increase in gas pressure from heat transfer fluid in a continuous heat transfer fluid system as it exits the evaporator. In alternative embodiments, the system can be used in a multi-zone application or to provide cooled air and water to a building. An embodiment primarily for use as an air conditioning unit is also described. Alternatively, fly-back technology is used to configure solar or wind powered DC current for use by a water generation system. In certain environments oil free compressors are employed in the water generation unit.

  • Patent number: 8696872
    Abstract: An improved water desalination system is disclosed, in which contaminated water such as seawater or brackish water is preheated and fed into a primary pressure vessel through a distribution head. The seawater is distributed from the distribution head over a non-adherent surface such as a plurality of silicone chords hanging below a distribution tank or a cone- and cylindrical-shaped surface. The water is exposed to a high temperature steam environment in the chamber to cause at least a portion of the water in the contaminated water to evaporate, while the remaining concentrated salts from the contaminated water fall to the bottom of the chamber. A portion of the steam in the primary pressure vessel is withdrawn to be condensed into fresh water. The energy withdrawn with the steam extracted from the primary pressure vessel is made up by a supplemental energy apparatus, such as a steam generator.
