Patents by Inventor James E. Kaucher

James E. Kaucher has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Processes and systems for liquefying natural gas
    Patent number: 6658892
    Abstract: Natural gas liquefaction systems are provided wherein dependent trains including only cryogenic heat exchanger systems are serviced by common components in the system such that individual components need not be included in each dependent train for servicing that function. Further, the common components are positioned near the LNG storage tanks which, in turn, are typically located a substantial distance from the trains. This significantly reduces capital costs and allows boil-off gas from LNG storage tanks to be used for cooling in addition to being used as a fuel gas.
    Type: Grant
    Filed: January 28, 2003
    Date of Patent: December 9, 2003
    Assignee: ExxonMobil Upstream Research Company

  • Processes and systems for liquefying natural gas
    Patent number: 6647744
    Abstract: Natural gas liquefaction systems are provided wherein the dedicated compression strings normally found in each liquefaction train of a multi-train LNG plant are replaced by common compression strings which, in turn, supply the respective refrigerants (e.g. propane and mixed refrigerant) to more than one of the multi-trains. This allows the refrigerants to be treated as a utility in that all of the refrigerants are supplied from a respective single source by the common compression strings.
