Méthodologie de conception de l'architecture d'intégration énergétique des procédés variables incluant des stockages thermiques et des systèmes de conversion d'énergie

Abstract : Many heat integration methods were developed to achieve high-energy efficiency in industry. Most of them are dedicated to continuous processes. However, statistics show that 50 % of processes are variable or batch. Hence: how to energetically integrate variable or batch processes including heat storages and energy conversion systems while minimizing the consumed exergy in the process? How to design utilities while considering the constraints on the energy network like the fluctuation of energy prices (imposed to reduce the energy consumption on peak hours) and the energy availability (resulting from the use of renewable energies)?The first part of the thesis presents the model to design the optimal architecture of heat integration in discontinuous processes including heat storages and energy conversion systems (heat pumps, tri-thermal machines, ORC etc.). This model allows the design of heat storages. The capacity and temperatures of energy conversion systems are also determined using this model. The objective is to reduce the consumed exergy in the process.The second part present the model for utilities design taking into account the real behavior of those under part load conditions or under constraints imposed by the network. It is an economic optimization.
