  • Sensor validation and value replacement for continuous emissions monitoring
    Patent number: 8650009
    Abstract: A continuous emissions model system is described that employs an emissions model that can determine emissions values from a plant for use in place of sensed emission data in the event of failure or lack of communication from a sensor. The emissions model itself receives inputs that may be based upon sensed data. Each emissions model input may be substituted with a modeled input. The modeled inputs, as well as the emissions model outputs maybe biased to render them more accurate. If any one of the emissions model inputs fails (e.g., becomes unavailable or is clearly erroneous), the corresponding modeled input may be utilized so long as the modeled input passes an acceptability test.
    Type: Grant

    Date of Patent: February 11, 2014
    Assignee: Rockwell Automation Technologies, Inc.
    Inventors: William Butler Forbes, Michael Eugene Sugars, Walter Edgar Hayes, IV, Eugene Boe, Scott Lawrence Jost, Richard Andrew Hovan, Keith Alex Smith

  • Gas sample probe for a gas analyzer
    Patent number: 6782767
    Abstract: A gas sampler (1) for a portable gas analyser, having a cooler or chiller (8) through which cooler or chiller (8) the gas sample is passed prior to being conveyed to a gas analyser, has the cooler or chiller (8) operable by means other than electrical power. The invention also includes a portable gas analyser provided with such a sampler (1).
