Análisis de la demanda eléctrica de una planta mezcladora de aceites lubricantes en búsqueda de la optimización de procesos (eficiencia energética) y la factibilidad de implementación de una granja de paneles fotovoltaicos que supla parcialmente la demanda de la planta

Abstract

CONDITION FOR PUBLICATION OF PROJECT. This degree project successfully described the electricity demand of an oil blending plant, using data-collection methodology that included interviews, electricity bills, and production data. Based on a detailed audit approach, it was possible to size a project for the implementation of photovoltaic panels, which would supply partially or all of the plant's demand. It also included energy efficiency proposals to reduce the plant's electricity demand. In addition, to photovoltaic panels, the energy efficiency proposals included the renovation of electric motors, staff training, reduction of reactive energy with capacitor banks, and analysis of energy quality. The last two proposals mentioned before could not be quantified, and staff training has not been fully implemented. Based on the efficiency proposals, feasibility and impact scenarios are developed, which were expected to meet the partial demand of the plant's sub-processes. It has been determined that the correct implementation of photovoltaic panels can fullfill the plant's total demand and be a project that allows the other proposals to be financed. In addition, the goal was to reduce electricity demand by at least 5%, and with the implementation of the most ambitious and comprehensive scenario, savings of between 4% and 24% can be achieved. Keywords: energy efficiency, electricity demand, photovoltaic panels, electric motors, training.
