  • Pressure-based control of fluidized bed reactor
    Patent number: 11117112
    Abstract: A method of controlling particle additions to a fluidized bed reactor includes measuring pressure fluctuations inside the fluidized bed reactor over a selected time period, determining a pressure parameter indicative of amplitudes of the pressure fluctuations, comparing the pressure parameter to a specified threshold, and controlling particle additions to the fluidized bed reactor when the pressure parameter deviates from the specified threshold.
    Type: Grant
    Filed: March 27, 2020
    Date of Patent: September 14, 2021
    Assignee: REC Silicon Inc
    Inventors: Kahl Brown, Matthew J. Miller, Benjamin Center, Gerald A. Zeininger, Stein Julsrud
