  • Multi-target scrubber
    Patent number: 8404033
    Abstract: A gas scrubber is presented. The gas scrubber comprises a nozzle that atomizes a liquid to form droplets. The droplets are preferably expelled from the nozzle in substantially a hollow cone spray pattern with a velocity of at least 4000 feet per minute. A stream of gas containing particulates that requires scrubbing interacts with the droplets. After the interaction, the gas-droplet combination impinges on a target. Preferred targets include droplets from a second nozzle, a ducting surface, or a throated passage.
    Type: Grant
    Filed: February 5, 2008
    Date of Patent: March 26, 2013
    Inventors: Richard S. Crews, John S. Crews
  • Turn-around scrubber
    Patent number: 7959721
    Abstract: A modular scrubbing system is presented. The scrubber system comprises multiple modules that allow a gas flow to turn-around return back through scrubbing modules. Contemplated modules include inlets, outlets, turn-arounds, and scrubbing modules.
