Publication number: 20110005395Abstract: Disclosed are apparatus and method to treat large amounts of flue gas from a pulverized coal combustion power plant. The flue gas is contacted with solid sorbents to selectively absorb CO2, which is then released as a nearly pure CO2 gas stream upon regeneration at higher temperature. The method is capable of handling the necessary sorbent circulation rates of tens of millions of lbs/hr to separate CO2 from a power plant's flue gas stream. Because pressurizing large amounts of flue gas is cost prohibitive, the method of this invention minimizes the overall pressure drop in the absorption section to less than 25 inches of water column. The internal circulation of sorbent within the absorber assembly in the proposed method not only minimizes temperature increases in the absorber to less than 25° F., but also increases the CO2 concentration in the sorbent to near saturation levels. Saturating the sorbent with CO2 in the absorber section minimizes the heat energy needed for sorbent regeneration.Type: ApplicationFiled: July 9, 2010Publication date: January 13, 2011Applicant: Southern CompanyInventors: Pannalal Vimalchand, Guohai Liu, Wan Wang Peng

Publication number: 20090293722Abstract: The invention relates to a new method for removing and recovering of acid gases from a gaseous mixture in an absorption plant by adding an organic acid to a stream of the rich absorbent in the desorber in order to release acid gas by shifting the acid gas equilibrium towards the gas side, and the organic acid is subsequently separated from the absorbent. With this method, the energy consumption of the process is substantially reduced. The invention also relates to an apparatus for performing this method.Type: ApplicationFiled: June 28, 2006Publication date: December 3, 2009Inventors: Hallvard F. Svendsen, Finn Andrew Tobiesen, Thor Mejdell, Karl Anders Hoff, Olav Juliussen

Patent number: 7611566Abstract: A cryogenic gas storage system for optimal desorption of adsorbed gases, wherein a gas storage material is subjected to enhanced, ample selected recirculation of gas of the same type as the adsorbed gas, at suitable temperature and pressure, so as to supply of heat energy to the material and thereby provide optimal desorption of the gas. Output gas is heated by ambient heat or dissipation heat utilizing at least one heat exchanger. A portion of the output gas goes to a gas consumer, the remainder is fed back to the container.Type: GrantFiled: May 15, 2006Date of Patent: November 3, 2009Assignee: GM Global Technology Operations, Inc.Inventors: Gerd Arnold, Ulrich Eberle, Dieter Hasenauer

Patent number: 7594956Abstract: A method for removing one or more strongly adsorbed components (SAC) from a process gas stream having SAC and other gaseous components adjusts the temperature of the SAC-laden process gas stream to be between about 80° and about 500° C. The temperature-adjusted process gas stream is contacted with a heat-exchange surface to transfer heat to an adsorbent, thus causing adsorbed SAC to be desorbed for collection, and to cool the process gas stream and remove any condensate from the cooled process gas stream. The cooled process gas stream is contacted with a cooled section of the adsorbent to adsorb SAC therefrom, producing a SAC-depleted process gas stream and a SAC-laden adsorbent. Desorbed SAC is withdrawn for collection and any adsorbent fines are withdrawing for collection.Type: GrantFiled: April 19, 2005Date of Patent: September 29, 2009Assignee: Adsorption Research, Inc.Inventor: Kent S. Knaebel
