Mark DeGenova 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).

  • Systems and methods for separating soft burned and hard burned calcium oxide
    Patent number: 11865583
    Abstract: Systems and methods to effectively sort calcined lime (quicklime) particles to produce products with more consistent size and burn time characteristics after the quicklime particles have been created and without the use of specialized additives. Specifically, such systems and methods sort the quicklime particles below a selected size into a softer burned and harder burned fraction based on their size. The fractions are burned in the kiln together and as a singular product, but can be classified from each other after calcining.
    Type: Grant
    Filed: April 8, 2019
    Date of Patent: January 9, 2024
    Assignee: Mississippi Lime Company
    Inventors: Mark DeGenova, Randy J. Griffard, David Venhaus
  • Systems and method for SOmitigation at high temperature injection locations
    Patent number: 11311839
    Abstract: Systems and methods for the use of highly reactive hydrated lime (HRH) in high temperature flue gas streams, namely those at greater than 400° F., such as are present before an air preheater (APH) to remove sulfur trioxide (SO3) from the flue gas.
