Eficiência energética em sistemas de geração, tratamento e distribuição de ar comprimido

Abstract

This work has the objective of presenting the potential of electric energy saving in compressed air systems, analyzing the real possibilities of reduction. The main components of a Compressor Plant was presented, demonstrating the generation, treatment and distribution of compressed air in an industrial plant. To identify the greatest energy losses of the system, were used a methodology based on the PDCA cycle and the 5W1H and 5 Why tools. After the system study, it was evidenced that the biggest losses of load of the system were caused by: - High fluid speed in pipes - Big distances between the generation of compressed air and end points users - Flow measurement system It was defined that the loss caused by the flow measurement system would be attacked by replacing the existing orifice plates by the Annubar. The result was satisfactory, since it generated a reduction of 12% in the consumption of electric energy of generation of compressed air and turn off of one of the compressors of the Central.
