Abstract
El presente trabajo realizado en el Sistema de Agua Fresca de una Faena Minera, consistió en un levantamiento de información de bombas centrífugas, caudales, alturas y configuración de estos elementos, con lo que se pudo obtener la información y puntos de operación de las estaciones. A raíz de esto se obtuvo la energía que ocupa el Sistema completo de Agua Fresca para poder cumplir con los requerimientos que se tienen desde otros sistemas. Siendo la energía y el agua recursos muy importantes dentro de la región, se busca que el uso de estos sea el más eficiente posible ya que son cada vez más caros.El Sistema de Agua Fresca está compuesto por 6 Estaciones de Impulsión de Agua Fresca y finalmente una Piscina de Agua Fresca por lo que el análisis se centró en la energía que se utiliza para bombear 1600 metros cúbicos por hora y lograr tener un mínimo de agua disponible en la Piscina de Agua Fresca. Para esto se analizó el consumo energético y las curvas características del sistema. En base a esto finalmente se propone un cambio en la configuración de los equipos, para disminuir el gasto energético y los costos por el funcionamiento de las Estaciones.En todas las Estaciones se identificó una baja eficiencia en el uso de la energía para impulsar el agua, llegando a sumar en total 16.000 MWh extras durante el año que se traducen en US$ 1.125.000 extras en el año. Por lo que se analizó las curvas de cada Estación como un Sistema obteniendo la Curva del Sistema. Como resultado de este análisis se logró determinar que la distribución de Caudal se puede mejorar en cuanto a Eficiencia y manteniendo la Eficacia del proceso, con una reducción de la cantidad de equipos por Estación. Se propone reducir a 2 la cantidad de bombas de la primera estación y a 3 bombas en las restantes Estaciones. Con lo cambios propuestos se lograría tener un ahorro de 27.000 MWh al año reflejados en US$ 1.900.000 durante el mismo periodo.
The present work carried out in the Freshwater System of a Mining Site, consisted of a survey of information of centrifugal pumps, flows, heights and configuration of these elements, with which the information and operation points of the seasons. As a result of this, the energy occupied by the complete freshwater system was obtained to meet the requirements that are available in other systems. Energy and water are very important resources within the region, its use is intended to be as efficient as possible since they are increasingly expensive.The freshwater system consists of 6 freshwater stations and finally a freshwater pool, so the analysis focused on the energy used to pump 1600 cubic meters per hour and achieve a minimum of water available in the pool. sweet water. For this, the energy consumption and the characteristic curves of the system were analyzed. Based on this, a change in the configuration of the equipment is finally proposed, in order to reduce the cost of energy and the costs for the operation of the Stations.In all the stations, a low efficiency in the use of energy was identified to boost water, adding up to an additional 16,000 MWh during the year, which translates into an extra US $ 1,125,000 in the year. Therefore, the curves of each Station were analyzed as a System obtaining the System Curve. As a result of this analysis it was possible to determine that the distribution of flow can be improved in terms of efficiency, maintaining the efficiency of the process, with a reduction in the number of equipment per station. It is proposed to reduce to 2 the number of pumps of the first station and 3 pumps in the remaining stations. With the proposed changes it would be possible to have a saving of 27,000 MWh per year reflected in US $ 1,900,000 during the same period.
