Resumo
This study investigates energy efficiency in an industrial electrical installation, focusing on power quality and optimizing the compressed air system, one of the largest energy consumers in industrial environments. The research explores practical and theoretically grounded measures to reduce energy consumption, enhance operational efficiency, and ensure the plant's sustainable growth—factors aligned with the United Nations' Sustainable Development Goals.
Key approaches include reducing operating and cut-off pressure, recovering heat from compression, and controlling leaks. Efficiency analysis is conducted through methods such as plant consumption profiling, energy demand diagnostics, and calculating specific indicators like energy consumption per unit and system performance. Economic indicators, including Net Present Value (NPV), Internal Rate of Return (IRR), and simple payback period, were used to compassess the financial feasibility and savings potential of the proposed improvements. Additionally, the study highlights the energy-saving potential of recovering compression heat for preheating water used in other industrial processes, demonstrating reductions in both electricity consumption and boiler fuel costs. The results emphasize the strategic importance of energy efficiency for energy-intensive industries, showing that the applied measures contribute
to more sustainable management and significantly reduce operational costs.
