APPLICATION OF DATA-RECONCILIATION AND OPTIMIZATION PROCEDURE TO HYDROGEN PLANT

Aim of this paper is to present an application of the reconciliation a nd optimisation package ORO (On-line Reconciliation and Optimisation) to an hydrogen plant of an existing refinery. The industrial plant per formances optimisation can be divided into three phases : gross errors detection, reconciliation and optimisation. All the difficulties link ed to each of these phases and the general approach are presented. The model reconciliation and optimisation skills were tested by comparing the predictions with plant measurements for two different plant capac ity conditions. Finally different optimisation strategies are shown, f or different production targets.
