Abstract: Systems and methods include a method for monitoring sensors. Readings of actual field sensors corresponding to virtual sensors of a virtual model are monitored. A deviation between an actual sensor reading (ASR) and a virtual sensor reading (VSR) is determined. When only the VSR is deviating and when sensor readings of sensors proximate to the actual sensor correspond to the VSR, then the ASR is invalid and the actual sensor requires revalidation/recalibration. When only the ASR is deviating and when sensor readings of sensors proximate to the actual sensor correspond to the ASR, then the VSR is invalid and the virtual sensor requires revalidation/recalibration. When both the VSR and ASR are deviating from design ranges and when sensor readings of sensors that are proximate to the actual sensor do not correspond to either the ASR or the VSR, then both the ASR and VSR are invalid, requiring revalidation/recalibration.

Abstract: An automatic online analyzer validation and calibration system receives operating parameter input signals from sensors, receives a measured value of a selected process variable from a physical analyzer, determines a difference between the measured value and an inferred value of the selected process variable determined by a controller based on the operating parameter input signals using an inferential analyzer; and if the difference between the measured value and the inferred value exceeds a threshold, initiates a recalibration of the physical analyzer or recalibration of the inferential analyzer. In one example, the automatic online analyzer validation and calibration is used in a gas dehydration system to validate and calibrate a physical moisture analyzer.

Abstract: Provided are embodiments of monitoring an industrial process that include determining a process structural model that defines operational characteristics of equipment used to perform the industrial process, determining an interface application to display a process flow diagram (PFD) for the process, obtaining an interface model for the interface application, determining (based on the process structural model) a grouped process structural model for the process, determining (based on the grouped process structural model) a routed process model for the process, and generating (based on the routed process model) the PFD for the process.
