Data Reconciliation for Refinery Hydrogen Network

Data reconciliation can be used for many applications namely as instrumentation maintenance, plant optimisation, advanced process control and many more. Data reconciliation is relatively new in Chemical Engineering field. Its applications especially in oil refineries are limited. Using process models (material balance) as constraints, data reconciliation enables us to obtain estimations of process variables by adjusting the measurements. This technique enhances the accuracy of the process variables as opposed to the measurements themselves
