Patents by Inventor Kenneth Devito

Kenneth Devito 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).

  • Advanced topologies for offshore power systems
    Patent number: 9249787
    Abstract: A variable speed compression system that is driven by a variable frequency high speed motor that receives power from a high frequency generation unit that is driven by a high speed gas turbine is provided. The speed of the turbine may be varied to control the output frequency of the high frequency generation unit, thus controlling the output of the compression system by controlling the speed of the turbine driving the generation unit.
    Type: Grant
    Filed: January 27, 2011
    Date of Patent: February 2, 2016
    Assignee: Dresser-Rand Company
    Inventors: Jose L. Gilarranz, Kenneth Devito
  • Method and system for reducing seal gas consumption and settle-out pressure reduction in high-pressure compression systems
    Patent number: 8596954
    Abstract: A compressor is disclosed having a shaft seal assembly and system that allows a high-pressure compressor to settle-out at a lower pressure level during shutdown. The seal assembly may be disposed about a portion of the shaft and define a blow-down seal chamber, the seal assembly including one or more gas seals in fluid communication with the blow-down seal chamber. A blow-down line is communicably coupled to the blow-down seal chamber to reference the blow-down seal chamber to a low pressure reference, such as a separate centrifugal compressor, or the like. Referencing the blow-down seal chamber to the low pressure reference reduces the required sealing pressure of the one or more gas seals. A valve may be disposed in the blow-down line and configured to regulate a flow of process gas leakage through the blow-down line.
