Eco Industrial Parks for Water and Heat Management

An EIP is a cluster of several processes that are not necessarily part of the same company, that share common infrastructure designed and operated to induce integration of materials exchange, discharge and waste treatment. Here three companies are concerned and the EIP is related to the management of fresh and waste water and the energy consumption. First each company is optimized alone according to fresh water and waste treatment, number of connections between processes, number of heat exchangers and energy consumption. Then the energy consumption of the EIP is minimized according to bounds on fresh water and wastewater treatment, the problem being parameterized by the number of heat exchangers and the number of connections. An example adapted from the literature is solved, showing the potentiality of the method for providing pertinent answers for reducing energy consumption, fresh water demand and wastewater treatment. The proposed methodology presents a real economic interest, with together a significant ecological impac
