  • OPTIMIZATION OF WET SCRUBBER PROCESS FLOWS THROUGH ONLINE MEASUREMENT AND CONTROL OF GASES ENTRAINED IN THE SCRUBBER LIQUID
    Publication number: 20200368642
    Abstract: A system and method for reducing foaming in a wet scrubber system. The system utilizes a device for measuring the volume of entrained gas in the wet scrubbing system, and automatically or semi-automatically adjusting one or more process parameters including: a flow rate of antifoam/defoamer chemistry in said wet scrubber; a flow rate of flue gas; and a flow rate of fresh water. The system allows real-time monitoring and control of the foam in said wet scrubber.

  • Hearing aid fitting system
    Patent number: 6574342
    Abstract: A method for fitting a hearing compensation device comprises selecting a plurality of loudness levels for a plurality of frequencies and comparing each loudness level for each frequency for perceived sameness. The loudness levels may then be adjusted as needed to achieve perceived sameness across the frequency spectrum. A gain curve for each frequency is calculated from the selected plurality of loudness levels.
