  • Methods and apparatus for an oxy-fuel based power cycle
    Patent number: 9388712
    Abstract: Methods and apparatus for an oxy-fuel combustion power cycle are provided, including converting gaseous carbon dioxide to liquid and/or supercritical carbon dioxide which may include the use of a cryogenic pump, removing a portion of the liquid and/or supercritical carbon dioxide from the cycle, combusting oxygen and a combustion fuel with the remaining liquid and/or supercritical carbon dioxide in an oxy-fuel combustor to generate steam and additional liquid and/or supercritical carbon dioxide which replaces the portion of the liquid and/or supercritical carbon dioxide sequestered from the cycle.
    Type: Grant

    Assignee: SOUTHWEST RESEARCH INSTITUTE
    Inventors: Klaus Brun, Marybeth G. Nored, Jason T. Gatewood, James J. Moore
  • Pressure recovery insert for reciprocating gas compressor
    Patent number: 8740581
    Abstract: A method of reducing pulsations in a reciprocating compressor system, the system having nozzles between cylinders and filter bottles of the compressor system, the nozzles attaching at ports of the cylinders and filter bottles. A special insert is designed to be placed in one or more of the nozzle. The insert is generally cylindrical, but has a narrowed throat, a flared inlet end, and a flared outlet end. The insert dimensions, such as the inner diameter of the throat and the distance from the throat to the outlet end are calculated to reduce pulsations as well as provide pressure recovery.
