Abstract
The rational use of utilities (electric energy, steam, and water) represents nowadays the great challenge to assure the competitiveness and sustainability of industries. The proposed work presents the minimization of the cost of steam and power generation in a petrochemical company, which has production of electric energy and steam by co-generation system. In this case, there is a balance to achieve between work and heat supply and this cannot be readily defined by heuristics or localized control loops. The application of an optimization model is proposed based on needs of energy demands, and readily exposing the scenery that minimizes the power and high pressure steam level production. It was observed a potential of economy of 46 t/h in the generation of steam in boilers and could be achieved a reduction of 6 MW of electric power consumption.
