  • Patent number: 8500886
    Abstract: Exhaust gas after coal or oil burning has moisture, which hinders carbon dioxide adsorption. It is necessary to completely remove this moisture with the minimum use of energy. The exhaust gas from the burning apparatus is first lowered of its temperature by passing through an total heat exchanger rotor, and the resultant gas which has low temperature and humidity is sent to a carbon dioxide adsorption rotor, thereby removing carbon dioxide from the gas, which is then sent through the total heat exchanger rotor with the resultant desorption of moisture adsorbed there and is exhausted to outside atmosphere, while the carbon dioxide adsorption rotor is desorbed of its carbon dioxide using water vapor, with the resultant very humid carbon dioxide to be sent to a processing system such as for underground burial.

  • Patent number: 8343259
    Abstract: Disclosed is a method for subjecting feed air to fractionation for recovery of a product oxygen fraction therefrom in a pressure swing adsorption (PSA) process utilizing a nitrogen-selective adsorbent (“NSA”) that is sensitive to water. The PSA process includes the steps of feed pressurization, production, equalization, and blowdown. The improvement to this PSA process commences with placing a bed of pre-treatment adsorbent between feed air and a bed of NSA. Next, a controllable valve is interposed between the pre-treatment adsorbent bed and the NSA bed. Finally, the controllable valve is kept closed during the steps of production, equalization, and when the process is idle. An advantageous NSA is LiX zeolite, Li-LSX zeolite, CaX zeolite, and similar adsorbents, particularly highly hydrophilic zeolites. Another feature of the disclosed PSA cycle is that the pre-treatment adsorbent bed blows-down while the NSA bed equalizes.

  • Patent number: 8268030
    Abstract: The invention provides wind energy use. One application provides wind energy use for water harvesting from natural humid air. The method is based on changing thermodynamic state parameters of ambient wind air portions passed through a device comprising convergent-divergent and wing-like components. Those components transform the ambient wind portions into fast and cooled outflowing air portions. A decrease in static pressure and temperature triggers condensation of water-vapor into water-aerosols. Another application of the method provides an effective mechanism for harvesting electrical energy from naturally warm air using renewable wind energy, including the wind inertia, internal heat, and potential energy stored in the air mass in the Earth's gravitational field. The electrical energy harvesting mechanism is also applicable to use of natural renewable energy of streaming water.

  • Patent number: 8221514
    Abstract: The invention provides an ecologically clean method and apparatus for water harvesting from air. The method is based on changing of thermodynamic state properties of air wind getting a rotation and passing through convergent-divergent nozzles. The apparatus is a water condensation engine exposed to humid wind. The constructive solution has no moving solid parts, and the incoming wind is an inherent moving component of the engine. It comprises a cascade of sequentially arranged horn-tubes and a set of stationary wing-like details. Those horn-tubes transform the wind into a fast and cooled out-flowing air flux coming-and-hitting upon the set of wing-like details, where the air portions are accelerated and eddying. The inner static pressure and temperature decrease in the air portions. The decrease in static pressure and temperature triggers off condensation of water-vapors into water-aerosols.

  • Patent number: 8216351
    Abstract: An Apparatus for purifying a feed stream containing carbon dioxide in which the feed stream, after having been compressed and dried, is partly cooled and then used to reboil a stripping column. Thereafter, the feed stream is further cooled and expanded to a lower operational temperature of the stripping column. A carbon dioxide product stream composed of the liquid column bottoms of the stripping column is expanded at one or more pressures to generate refrigeration, then fully vaporized within the main heat exchanger and compressed by a compressor to produce a compressed carbon dioxide product. Refrigeration is recovered in the main heat exchanger from a column overhead stream extracted from the stripping column within the main heat exchanger either directly or indirectly by auxiliary processing in which carbon dioxide is further separated and optionally recycled back to the main compressor used in compressing the feed stream.
