Abstract:
1. A system for on-line monitoring of operation of a process in a process plant having a process control system to control the process in connection with process measurements indicative of the operation of the process, the system comprising: a process simulation module to receive one or more process measurements and input at least one of the received process measurements into a model corresponding to one of a plurality of physical devices within the process plant, the model modeling the behavior of the physical device in the process, the simulation module using the model to simulate the operation of the process and generating model data indicative of a simulated representation of the operation of the process, the model data including data of an unmeasurable process parameter; an analysis module to implement a multivariate statistical analysis of the operation of the process based on the model data and the process measurements; one or more computer-readable media to store configurations of the process simulation module and the analysis module; one or more computer-executable execution engines for implementation of the configurations of the process simulation module and the analysis module to enable the on-line monitoring of the process based on communications with the process control system during the operation of the process; and a process graphic stored in the one or more computer-readable media for use by the one or more execution engines in generating a user interface having a graphic display of the plurality of physical devices modeled by the process simulation module, wherein the graphic display is configured to provide a plurality of display elements representative of current operating conditions of the plurality of physical devices in accordance with the multivariate statistical analysis.
