Data reconciliation is one of the important steps in Heat Exchanger Network (HEN) retrofit. Correctly performed data reconciliation can help in Heat Integration (HI) analysis. In this work, iterative method for reconciling heat exchanger network HI is explored. This work addresses the limitation encountered by the iterative method previously published. Several solution strategies have been evaluated. The work also proposes a procedure for data reconciliation at Total Site level. An illustrative case study shows the effectiveness of this iterative method. The iterative method provides a relatively good result, when compared with simultaneous method.
