On-line data reconciliation in chemical plants

Abstract Knowledge of massbalance and the information carried by massflows in the form of components, temperature and pressure strongly effect product quality, plant safety and plant profitability. The paper reports our experience with ON-LINE data reconciliation gathered since 1989, on two chemical plants.

On-line estimation of reactor key performance indicators: An industrial case study

Abstract On-line monitoring of key performance indicators of chemical processes is a crucial factor for fast operator response to abnormal operating conditions and for the long term optimization of the process operating point. While the scientific background for the design of such estimation algorithms has been well developed, the realization in the industrial environment is hardly documented. In this paper, the design and the implementation of on-line key performance indicators for a industrial Ketene reactor are described. The benefits of the on-line performance estimation were an additional 5% of productivity potential.
