Patents by Inventor Jaleel Valappil

Jaleel Valappil 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).

  • Multi-stage compressor/driver system and method of operation
    Patent number: 8591199
    Abstract: An improved system and methodology for starting up a gas-turbine driven multi-stage compressor. The improvement involves isolating individual compression stages and creating positive pressure in each stage prior to initiating rotation of the compressor/driver system. The isolation of individual compression stages allows the turbine to reach normal operating speeds with substantially no supplemental power from an auxiliary source.
    Type: Grant
    Filed: January 11, 2007
    Date of Patent: November 26, 2013
    Assignee: ConocoPhillips Company

  • Anti-bogdown control system for turbine/compressor systems
    Patent number: 7712299
    Abstract: An anti-bogdown control system monitors and regulates operation of a turbine and a compressor to prevent underspeed trip of the turbine while avoiding surge of the compressor. A turbine speed controller receives a turbine speed signal and a turbine temperature signal, generates a surge margin setpoint, and regulates overfiring of the turbine. A surge margin controller associated with the compressor receives the surge margin setpoint from the turbine speed controller and receives a load signal from one or more sensors and modulates a compressor throttle valve so that the compressor operates at a surge margin that is approximately equal to the surge margin setpoint. In a system with multiple compressors driven by a single turbine, a surge margin controller is associated with each compressor.
