| 20090007783 | Method for Drying a Gas and Device Applied Thereby - Method for drying a gas from a compressor ( | 01-08-2009 |
| 20090301300 | Gas Dryer - A gas dryer having an inlet for receiving a wet gas; at least one vessel containing at least a desiccant for absorbing moisture from a wet gas passing through the desiccant in a first direction under pressure and for desorbing the desiccant by passing a second gas under a partial vacuum in a direction counter to the first direction during a warming and a cooling phase of regeneration; a means for generating a partial vacuum in the vessel; and an outlet for expelling dried gas from the vessel. | 12-10-2009 |
| 20100089236 | Oxygen Binding of Nanoparticulate Metal Complexes - Solid nanoparticulate transition metal complexes of Co(II) salen exhibit reversible oxygen absorption in a near stoichiometric manner. In contrast, no measurable oxygen binding was observed with unprocessed Co(II) salen. | 04-15-2010 |
| 20110154986 | HIGH EFFICIENCY GAS CONCENTRATING APPARATUS AND METHOD OF CONTROLLING HIGH EFFICIENCY GAS CONCENTRATING APPARATUS - A high efficiency gas concentrating apparatus includes an air compressor for supplying high pressure air, first and second adsorption towers that are disposed above the air compressor and communicating with the air compressor to adsorb nitrogen and concentrate oxygen as the high pressure air is alternately supplied thereto, first and second concentrating passages that are disposed above the respective first and second adsorption towers to discharge the concentrated oxygen, and a cleaning tank that is disposed between the first and second concentrating passages to receive a portion of the concentrated oxygen from one of the first and second adsorption towers, temporarily store the received concentrated oxygen therein, and alternately remove adsorbed nitrogen by supplying the temporarily concentrated oxygen to the other of the first and second adsorption towers. | 06-30-2011 |
| 20110271833 | Adsorbent Bed Support - An adsorbent vessel and process for using the adsorbent vessel subject to thermal swing expansion/contraction is disclosed where the adsorbent vessel comprises a support screen affixed to the adsorption vessel subject to thermal swing expansion/contraction and where a first section of the support screen extends along a portion of the length of the adsorption vessel subject to thermal swing expansion/contraction in the axial direction and comprises apertures permitting gas permeation and where the first section of the support screen has a cross-section in the axial direction that is arcuate. | 11-10-2011 |
| 20120222554 | Rapid Temperature Swing Adsorption Contactors for Gas Separation - Novel adsorbent contactors and methods are disclosed herein for use in temperature swing adsorption for gas separation applications, as well as for heat exchange applications. | 09-06-2012 |
| 20130312606 | SYSTEM AND METHOD FOR CARBON DIOXIDE CAPTURE AND SEQUESTRATION FROM RELATIVELY HIGH CONCENTRATION CO2 MIXTURES - A system and method of reducing the net carbon dioxide footprint of an industrial process that generates power from the combustion of hydrocarbon fuels in which ambient air is admixed with up to 50% by volume of an effluent gas from the power generator of the industrial process, in order to substantially increase the CO | 11-28-2013 |
| 095105000 | Feed gas or constituent thereof is sweep gas | 3 |
| 20090000475 | Zeolite membrane structures and methods of making zeolite membrane structures - Inorganic membrane structures of high stability, high permeability, and large surface area. Zeolite membranes can be disposed onto an intermediate pore size modification layer which reduces the pore size of the inorganic porous support. The intermediate pore size modification layer minimizes the defects in the zeolite membrane and provides a more continuous and uniform zeolite membrane. The inorganic membrane structure can be in the form of a honeycomb monolith. The applications for the zeolite membranes include, for example, membrane ultra-filtration of gas or liquid fluids, biological assays and cell culture surfaces. | 01-01-2009 |
| 20100071552 | A Method Of Removing Nitrous Oxide - Hydroxylamine is formed in a reactor through a partial hydrogenation of nitric oxide gas (NO) with hydrogen gas (H | 03-25-2010 |
| 20130000486 | METHOD FOR THE ADSORPTIVE DRYING OF PURIFIED BIOGAS AND FOR REGENERATING LADEN ADSORBENTS - In a method for adsorptively drying purified biogas and regenerating laden absorbents, foreign matter is not allowed to enter the purified biogas, the content of methane in the gas remains virtually unchanged and the effort involved in regenerating the laden adsorbent is reduced. Drying and regeneration are effected in a closed biogas cycle, wherein separate layers based on silica gel and molecular sieves are used as the adsorbent. The biogas to be dried first flows through the silica gel layer. The adsorbent is regenerated with exclusively heated, dried biomethane having a temperature of up to 150° C. which, after contact with adsorbent, is recirculated to the outflow of purified biogas. After regeneration, the bed is cooled by biomethane, which is subsequently recirculated to the outflow of purified biogas. Methane-containing water accumulating during drying and regeneration is recirculated to the biogas generation and/or purification. | 01-03-2013 |
