Levantamento dos potenciais de racionalização energética e adequação de motores de indução trifásicos em uma indústria sucroalcooleira: um estudo de caso

Abstract

The present work aims to present a study to replace old three-phase induction motors (MITs), installed in distillation, drying and sugar testing sectors, as well as in the manufacture of yeast in a sugar and alcohol plant, with motors optimized for areas with explosive atmosphere and more efficient from an electrical point of view. This replacement aims to ensure compliance with conditional safety standards, eliminating the risks of explosions and fires associated with the use of unsuitable engines. The work guide begins with the presentation of concepts and theories about the production processes of an industry producing sugar, alcohol and dry yeast, in addition, definitions related to MIT and criteria for adapting specific areas are also included. . Based on the data collected regarding MITs and the area classification study carried out by the specialized company, it is possible to define which equipment should be installed in each sector based on their classification zones. Finally, through asset mapping it is possible to quantize the potential for energy rationalization, considering the return since the energy saved is sold as export for export. It can be concluded that the MITs chosen for adaptation and the proposed schedule satisfactorily meet the objective of adapting the areas, in addition, the energy efficiency study shows a financial return in terms of replacing the equipment, therefore, in addition to meeting the standards of safety there is a reduction in costs in terms of electricity consumption.
