Abstract: A spiral double-tube structure including an inner tube for introducing a solvent vapor resulting from vaporization within a distillation still and an outer tube which a coolant gas cooled by an outdoor machine is passed through is disposed in a buffer tank; the solvent vapor is directly cooled from the surrounding area by the coolant gas with a large temperature difference and thus condensed into a liquid state; by means of an ejector, the liquid is mixed with the solvent suctioned from the buffer tank and returned into the buffer tank; since the solvent in the buffer tank is also directly cooled by the coolant gas, the cooling efficiency is high; accordingly, both the solvent vapor generated from the distillation still and the solvent in the buffer tank for reducing the pressure inside the distillation still can be efficiently cooled without using cooling water, and downsizing of the apparatus can also be attained.

Abstract: A photovoltaic-thermal (PV-T) system and a method of cooling photovoltaic (PV) cells in the system is described herein. Energy from an excitation source such as the sun hits the PV cells in the PV-T system causing heating that reduces PV efficiency. The PV cells are cooled by fluid in an intact heat-transfer system making a heated water byproduct while the PV cells release a form of energy. In addition, the PV-T system can be implemented in a desalination plant to harvest energy and heat for desalination processes. The present invention also includes methods for transferring heat from PV cells to the earth to improve PV performance and reduce thermal shock to the PV cells.

Abstract: The fluid density-driven desalination system is an evaporative desalination system utilizing gases having differing molecular weights from that at of water vapor in order to assist in the evaporation and condensation of pure water vapor. Evaporation of pure water from a saline solution through a first capillary evaporator plate is assisted by a first gas having a molecular weight less than that of water vapor, thus driving the evaporated water vapor downwardly for collection and condensation. Similarly, evaporation of pure water from brine through a second capillary evaporator plate is assisted by a second gas having a molecular weight greater than that of water vapor, thus driving the evaporated water vapor upwardly for collection and condensation.

Abstract: A device for producing drinking water is described, said device comprising supply means (10, 10a, V1, 11) able to provide a quantity of inlet water; a distillation system (20, 21, 23) able to distil said quantity of inlet water so as to obtain a corresponding quantity of distilled water; a salt supply system (40) able to provide, in the form of a concentrated aqueous solution, at least one reserve supply of salts necessary for obtaining water which may be defined as drinking water; and a mixing system (30) able to receive at least a part of this salt reserve and mix it in a controlled manner with the quantity of distilled water, at the same time aerating the latter, so as to provide drinking water; and a dispensing tap (50) able to dispense this quantity of drinking water.
Abstract: The present invention is directed toward a method and a system for reducing the amount of fluid in a biological mass comprising solids and fluid in the form of liquid and gas. The system includes a temporary storage container for receiving and temporary storing a biological mass, at least one separator arranged to receive the biological mass from the temporary storage container and separate at least a portion of the fluid of the mass from the solids of the mass, a solids container for receiving the solids fraction separated from the biological mass, and a liquid-purifying device arranged to purify the liquid which is separated from the mass by means of the separator. The system is substantially fluidtight towards the surroundings and the separator includes a screen cloth and a device for inducing a fluid flow. The fluid flow is arranged to carry a portion of the liquid out of the mass and through the screen cloth, the essential part of the fluid flow has been recirculated in the system (1).
Abstract: The system contains a liquid-tight enclosure. An input source is connected to the liquid-tight enclosure for inputting water into the liquid-tight enclosure. A heating element is in thermal communication with at least a portion of the water within the liquid-tight enclosure. A plurality of substantially vertical plates are aligned along a substantially horizontal axis within the liquid-tight enclosure. Each of the substantially vertical plates has an opening. A groove is formed along each of the substantially vertical plates. A first end of the groove on each of the substantially vertical plates is proximate to the opening. At least one manifold extends through a plurality of the openings of the substantially vertical plates. The manifold is in fluid communication with a plurality of the first ends of the grooves. An output opening is formed in the liquid-tight enclosure. The output opening is arranged in fluid communication with the manifold.

Abstract: The present invention is an improved type of distillation of water. Usual distillation is related to a liquid's boiling point. However, it is possible to distill significant quantities of water at temperatures well below the boiling point. During distillation a compound is taken from a liquid-phase to the gas phase and then condensed to the liquid again to get a pure liquid. The present invention uses water sprayed and adsorbed onto a solid surface such as micro-powder made from wood as a starting material. Absorbing water onto such a surface results in rapid evaporation with a relatively low temperature gradient when the water and particles are agitated. The present invention could be characterized as solid-phase distillation.
Abstract: An improved system for reboiling a liquid in a separator is disclosed. The system includes a separator having a bottom fractionation tray, a conduit for removing liquid accumulated on the bottom fractionation tray, and a reboiler for reboiling liquid removed from the bottom fractionation tray to form a vapor which is returned to the separator by another conduit and below the spatial location of the bottom tray. The vapor returned to the separator is at least substantially sealed off from fluid flow communication with the accumulated liquid removed from the bottom fractionation tray.
Abstract: Removal of water in a vinyl chloride monomer purification system is achieved through (1) providing a distillation column for separation of a liquid admixture of vinyl chloride, hydrogen chloride, and water into (a) an essentially pure vinyl chloride product stream and (b) a hydrogen chloride distillate stream; and (2) placing a drying system in fluid communication with the distillation column midsection at a connection point where the water is at sufficient concentration to provide a useful mass transfer flux of water from a withdrawn midsection stream into a drying agent.
