In this paper, a rigorous MILP formulation for grass-root design of heat exchanger networks is developed. The methodology does not rely on traditional supertargeting followed by network design steps typical of the Pinch Design Method, nor is a non-linear model based on superstructures, but rather gives cost-optimal solutions in one step. Unlike most models,(More)
allows the rigorous one-step grassroots design of heat exchanger networks. For the retrofit, we consider the cases of addition and relocation of heat exchangers allowing control of repiping costs as well as splitting. While previous works considered area reduction in existing exchangers, they very rarely took into account the associated cost, which we now(More)
The purpose of this paper is to discuss the role of heat pumps in total site heat integration. It will be shown how heat pumps can help de-bottleneck heat transfer so that maximum energy savings are attained. Non-linear targeting models to get maximum cost savings and optimum heat pumping temperature levels are presented. Finally, the paper describes(More)
