  • Method and apparatus for controlling temperature in selective catalytic reduction systems
    Patent number: 11873749
    Abstract: An apparatus for use with a combustion apparatus and an associated Selective Catalytic Reduction (‘SCR’) device, comprises a temperature sensing device configured to measure the temperature of an exhaust from the combustion apparatus; and an injection unit configured to inject hydrogen into a feed of oxidizer to the combustion apparatus. An amount of hydrogen is added to an oxidiser feed of the combustion apparatus sufficient to reach a temperature in the exhaust of at least about 270° C.
    Type: Grant
    Filed: January 25, 2021
    Date of Patent: January 16, 2024
    Assignee: NOBLE DRILLING A/S
    Inventors: Jan Høffner, John Røn Pedersen

  • MOTION-STATE DEPENDENT OPERATION OF KINETIC GENERATOR ON A MARINE VESSEL OR PLATFORM
    Publication number: 20210197935
    Abstract: A motion-state dependent method for operating a kinetic generator on a marine vessels or platform includes determining a motion state of the marine vessels or platform, and imposing a limit on at least one of charging and discharging of the kinetic generator based upon the motion state to keep the kinetic generator within a safe operating range.
