23 European Symposium on Computer Aided Process Engineering

This paper presents a novel MILP-based iteration method for intensifying heat transfer to improve energy recovery in heat exchange networks (HENs) with topology modifications. A new optimization framework has been proposed to deal with the nonlinear computational difficulties due to the combination of conventional HEN retrofit (topology modifications) with heat transfer intensification. An industrial scale case study is carried out to demonstrate the validity and soundness of the proposed approach.
