Description:
Models are the key element for validating and reconciling process data, whether from process instrumentation or the lab. Combining models with statistics and heuristics can provide a viable mechanism for validating instrumentation, analyzers, laboratory data and other information required for control, advanced control, optimization and corporate information Advances in empirical techniques such as neural networks, PLS, PCR, and other regression methods, have made model-based validation and reconciliation systems economically attractive. Model-based systems provide the added value of being able to replace suspect data with reasonable estimates based on redundant information existing in the plant. This paper describes how empirical models are applied for validation and reconciliation. An example of an operating model-based validation system in a process plant is presented.
