  • Patent number: 8894752
    Abstract: An air dryer includes first and second flow paths. Each flow path includes a check valve that prevents fluid flow into the flow path and an exhaust valve having an open position that permits fluid flow out of the flow path and a shut position that prevents fluid flow out of the flow path. A diverter valve has a first position that provides fluid communication to the first flow path and a second position that provides fluid communication to the second flow path. An interlock operably connected to the diverter valve and the exhaust valves prevents positioning the diverter valve to the first position when the exhaust valve in the first flow path is in the open position and prevents positioning the diverter valve to the second position when the exhaust valve in the second flow path is in the open position.

    Abstract: The invention provides gas purification systems for the recovery and liquefaction of low boiling point organic and inorganic gases, such as methane, propane, CO2, NH3, and chlorofluorocarbons. Many such gases are in the effluent gas of industrial processes and the invention can increase the sustainability and economics of such industrial processes. In a preferred system of the invention, low boiling point gases are adsorbed with a heated activated carbon fiber material maintained at an adsorption temperature during an adsorption cycle. During a low boiling point desorption cycle the activated carbon fiber is heated to a desorption temperature to create a desorption gas stream with concentrated low boiling point gases. The desorption gas stream is actively compressed and/or cooled to condense and liquefy the low boiling point gases, which can then be collected, stored, re-used, sold, etc.

  • Patent number: 8075677
    Abstract: A carbon canister with a valve activated by the weight of nearly saturated or saturated carbon communicates with piping from an underground tank. The invention includes carbon within a casing inside a canister, a weight actuated valve, and piping in communication with the atmosphere. When an ORVR vehicle refuels, the pressure lowers in the tank that draws air into the canister. After refueling, the tank remains subject to conditions that generate hydrocarbon vapors. Those vapors then return to the canister and adhere to the surface of the carbon. The carbon, heavier with hydrocarbons, lowers the canister and closes the weight actuated valve. Closing the valve returns pressure control to an external pressure vacuum relief valve. The next refueling draws in atmospheric air to purge the hydrocarbons in the canister and thus lighten it. A secondary purge valve also removes hydrocarbons from the canister. Once the carbon lightens, the inlet valve opens and the vapors return to the canister for adsorption.

  • Patent number: 7827972
    Abstract: An adsorption/desorption device is communicated with an upper space of a fuel tank via a vapor passage. The adsorption/desorption device is configured to selectively adsorb or desorb air components contained in vapor. The adsorption/desorption device and the vapor passage are not communicated to the external atmosphere. The fuel tank is provided with a pressure detecting device for detecting the internal pressure of the fuel tank. A pressure regulating device is provided to the vapor passage for controlling and maintaining the pressure applied to the adsorption/desorption device. When the internal pressure of the fuel tank is higher than the atmospheric pressure, the internal pressure of the fuel tank is pressure-fed to the side of the adsorption/desorption device via the pressure regulating device until the internal pressure of the fuel tank becomes in equilibrium with the atmospheric pressure.

  • Patent number: 7704304
    Abstract: An improved sieve bed design to manage breakthrough and the mass transfer zone by way of volumetric division. An empty space in the product end is separated from adsorbent-filled sieve space in the feed end by a mid-diffuser plate. The ratio of the empty product end void space to the adsorbent filled sieve space within a sieve bed may be determined by the relative percentages of the gasses to be separated and the bulk loading factor of the molecular sieve. A product end void space of the correct volume may ensure the maximum volume of nitrogen has been adsorbed before breakthrough occurs. In operation, pressure in the sieve bed empty space and sieve filled space may be equal at any instant. This contains breakthrough to the location of the mid-diffuser plate. The mass transfer zone may be static at the point of the mid-diffuser plate and as such, gas separation is a function of pressure within the bed.

The cover unit has an exhaust opening and an air supply opening. Further, the apparatus is equipped with moisture recycle unit (2) fitted to the worker so as to simultaneously carry out the two processes consisting of the adsorption process of introducing moist air, effecting adsorption of the water contained in the air on an adsorbent and emitting dry air and the regeneration process of introducing dry air, effecting evaporation of the water adsorbed on the adsorbent into the dry air and emitting moist air. Still further, the apparatus is equipped with exhaust hose (3) connecting the exhaust opening of the cover unit to the moisture recycle unit and with air supply hose (4) connecting the moisture recycle unit to the air supply opening of the cover unit.

  • Patent number: 7578872
    Abstract: An underground fuel tank releases vapors depending upon air pressure. A vapor pressure management system has a canister for a vapor recovery system that connects with piping from an underground tank and has carbon therein along with appurtenant pipes and valves. When an ORVR vehicle refuels, the pressure lowers in an underground tank that draws air through the valves into the canister. After refueling an ORVR vehicle, environmental conditions generate hydrocarbon vapors. Barometric pressure drops and evaporated fuel during long refueling lulls produce hydrocarbon vapors at an increased pressure. Those hydrocarbon rich vapors then return to the canister of the system where the carbon binds the hydrocarbons while releasing air to the atmosphere. The refueling of the next ORVR vehicle draws in atmospheric air to purge the hydrocarbons retained in the canister of the system.
