  • Patent number: 10310497
    Abstract: A method and apparatus capable of monitoring performance of a process and of the condition of equipment units effecting such process is disclosed. A process model predicated upon mass and energy balancing is developed on the basis of a plurality of generally nonlinear models of the equipment units. At least one or more of such equipment models are characterized by one or more adjustable maintenance parameters. Data relating to mass and energy transfer within the process is collected and is reconciled with the mass and energy characteristics of the process predicted by the model. The condition of the equipment units and process performance may then be inferred by monitoring the values of the maintenance parameters over successive data reconciliation operations.

  • Patent number: 7418354
    Abstract: A method for detecting a leak in a fluid-conducting conduit is disclosed herein. The method includes generating a first flow vector variation pattern representative of fluid flow through the conduit under known conditions. The method also includes collecting flow data from flow sensors positioned along the conduit. In addition, a second flow vector variation pattern is generated based upon the flow data. The first flow vector variation pattern and the second flow vector variation pattern are then compared in order to detect whether a leak exists in the conduit.
