Data Reconciliation for Refinery Hydrogen Network.
Masters thesis, Universiti Teknologi PETRONAS.
Abstract
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.
