  • Patent number: 8951339
    Abstract: A system for compressing and drying a gas generally includes a compressor having multiple stages of compression and a dryer. The compressor includes a first heat exchanger and an after-cooler each of which utilizes a fan. A sensor is provided downstream of the after-cooler. The fan and sensor are in communication with the controller. A final stage compressed gas outlet of the compressor provides hot compressed gas to the regenerative portion of the dryer. Utilization of the final stage compressed gas for regeneration while also utilizing the compressor's after-cooler provides gas which is sufficiently hot to regenerate desiccant in the dryer and allows the communication between the sensor, the controller and compressors to remain intact.

  • Publication number: 20140190349
    Abstract: In a dehydration equipment, a regenerative gas heater heats a portion of CO2 gas dehydrated in an adsorption tower that is performing an adsorption process and supplies the gas to an adsorption tower that is performing a regeneration process. A regenerative gas preheater performs heat exchange between the CO2 gas that will be supplied to a regenerative gas heater and the CO2 gas sent out from the adsorption tower that is performing the regeneration process. Then, in the dehydration equipment, a regenerative gas cooler cools the CO2 gas that has been sent out from the adsorption tower that is performing the regeneration process and exchanged heat, separates water from the cooled CO2 gas, and returns the resulting gas to the adsorption tower. Thus, the dehydration equipment can prevent an increase in utility consumption due to the regeneration process.

    Abstract: A carbon dioxide (CO2) removal system includes a first sorbent bed and a second sorbent bed. Each of the first and second sorbent beds has a molecular sieve sorbent for adsorbing or desorbing CO2. One of the sorbent beds adsorbs CO2 and the other of the sorbent beds desorbs CO2. The first and second sorbent beds are thermally connected to transfer heat between the sorbent beds.

  • Publication number: 20070283811
    Abstract: A core unit of a dehumidifier comprises two towers and an upper and a lower air valve. The two towers are mounted in parallel between the upper and lower air valves and respectively filled with a drying agent. Two control valves are respectively connected to the corresponding tower through the lower air valve. When pressurized air flows into the lower air valve, the lower air valve determines that the air go to one of the two towers linked to the other tower by an equalizing slot, causing a difference in air pressure between the two towers. When the air pressure of the two towers is equal, the lower air valve changes the tower to receive the pressurized air and allows the drying agent in the other tower to dry out. Therefore, the two towers generate dry air alternately whilst reducing manufacturing costs.

  • Patent number: 7300498
    Abstract: A system and method for removal of solvents, or other materials, from an exhaust stream, uses an active adsorption bed and a bed that is periodically regenerated. Electrically heated nitrogen may be used to regenerate the beds. A portion of the exhaust stream to be cleaned is diverted to a heat exchanger, so as to pre-heat the nitrogen used for regeneration. Liquid nitrogen, preferably from the same source as that used to provide gas for regeneration, is directed to the active bed, lowering its temperature and increasing its efficiency. The invention avoids the need for the use of steam to heat the nitrogen, and provides a system that is more efficient than those known in the prior art.

  • Patent number: 7294173
    Abstract: A method for desorption and recovery of desorbed compounds, including the steps of generating a recirculating stream of inert gas (1), which passes through the material (2) to be desorbed, heating such inert gas stream to a temperature sufficient to cause the desorption process, yielding a gas effluent (3) from such recirculating stream of inert gas (1) in such a manner that the recirculated gas keeps a constant pressure, cooling such gas effluent to cause condensation of the desorbed compounds contained in such gas effluent (3), the cooling being obtained at least partly by pressure vaporization of a cryogenic fluid (4), and feeding such recirculating gas stream (1) by using at least a part of such pressure vaporized cryogenic fluid that was previously used to cool at least a part of the gas effluent (3).

  • Patent number: 6960243
    Abstract: A method and apparatus for the extraction of water from a gas stream, such as atmospheric air. The method includes contacting the gas stream with a porous adsorbent material having a surface modifying agent adsorbed on the surface of a porous support. The surface modifying agent creates a hydrophilic surface for the adsorption of the water. After the water is adsorbed into the pores, the surface modifying agent is selectively desorbed from the surface. The water then evaporates from the pore and can be collected in a condenser. The method and apparatus of the present invention advantageously operate in a substantially isothermal manner, thereby reducing the size and power consumption of the device. The device can advantageously be used to extract potable drinking water from atmospheric air.

  • Patent number: 6869464
    Abstract: A device for absorbing atmospheric moisture includes a support member with a net extending therefrom. The net includes a super absorbent polymer that has the property of being able to absorb a multiple of the polymer mass in atmospheric water and to thereafter release the water in response to an external stimulus. The device is in this way reusable. The device has particular application in the clearing of fog, manure odor clearance, and collection of potable water in remote locations. A process for extracting atmospheric moisture is also detailed that includes the step of extending a super absorbent polymer net into contact with an atmosphere. Thereafter, with that being in contact with the atmosphere for a sufficient amount of time moisture is absorbed from the atmosphere. The application of a stimulus to the super absorbent polymer containing atmospheric moisture causes the release of liquid water therefrom. The super absorbent polymer is then suitable for reuse to again absorb atmospheric water.

  • Patent number: 6863711
    Abstract: A system for recovering water from the atmosphere includes water sorbent assembly composed of a water adsorbent material and a heat exchanger. The water adsorbent material traps water present within the air drawn through the sorbent assembly. Once the sorbent assembly is fully saturated, exhaust gases generated from a power plant are routed through a heat exchanger in thermal contact with the water adsorbent material to remove water within the sorbent assembly into a condenser, and from the condenser to a water storage container.

  • Patent number: 6764755
    Abstract: A channelized sorbent material comprises porous sorbent particles characterized by an average pore diameter. Each sorbent particle has at least one interior channel of an average transverse dimension (i.e. transverse diameter) that is at least ten times larger than the average pore diameter of the porous sorbent particle. The interior channel may constitute a single cylindrical through-bore in the sorbent particle, or alternatively, an array of intersecting or non-intersecting channels. The porous sorbent particles preferably comprise bead activated carbon particles. Such channelized sorbent material is particular useful as sorbent media in an adsorption-desorption apparatus for storage and dispensing of a sorbable fluid.

  • Patent number: 6702876
    Abstract: An ion exchange scrubber has a housing, and a partition plate installed within the housing. The partition plate partitions an inner space of the housing in longitudinal direction into two chambers that are filled with a predetermined amount of aqueous solution. The upper end portions of the two partitioned chambers communicate with each other. At least one cartridge is installed at the upper portion and has an ion exchange resin. The ion exchange resin removes a harmful substance contained in the gas. By repeatedly pumping the aqueous solution from one side chamber to the other side chamber, and immersing and cleaning the contaminated ion exchange resin in the aqueous solution, the contaminated gas can be effectively processed even with a small amount of water.
