Retrofit and optimisation of industrial heat exchanger networks: A complete benchmark problem

The purpose of this paper is to present a comprehensive formulation for an industrial benchmark problem. This could hopefully challenge the developers of HEN synthesis methods to address the rigorous problem. The paper is organised as follows: firts the traditional problem formulation is reviewed, then the general rigorous problem formulation is outlined, followed by a complete industrial benchmark problem. Finally a simplified formulation is derived from the full problem. Due to the space limitation it is not possible to include solutions to the specified problems, but these will be available for those interested.
