  • Reduction of CO and NOx in regenerator flue gas
    Patent number: 7470412
    Abstract: A hot oxygen stream is fed into a catalyst regenerator flue gas stream that contains carbon monoxide to remove carbon monoxide. NOx precursors such as NH3 and HCN are converted into N2 and if NOx is present in the flue gas stream the addition of the hot oxygen stream lowers the amount of NOx present.

  • Controlling jet momentum in process streams
    Publication number: 20080006225
    Abstract: A gaseous process stream that can be directed into a workspace or toward a workpiece is formed by feeding fuel, oxidant and process material into a thermal nozzle. The fuel combusts in the thermal nozzle with the oxidant and with combustible components, if any, of the process material, to form the gaseous process stream which is emitted from the thermal nozzle at high and controllable velocity and momentum.
