dc.description.abstractThis paper aims with methodologies and indicators for evaluating the impacts of freshwater use, the existing methods fundamentally analyze the amount of water used in relation to the impacts caused. Taking into account that there is a recognized need to consider the impacts, specifically on life cycle bases, the problem is that the data is considered insufficient or unreliable in the life cycle databases of water use, in addition not The method for evaluating the impact of the life cycle coincides with regard to the estimated impacts on the use of fresh water. These difficulties are highlighted and the advantages, limitations, differences in the results between different methods are analyzed, and the need for an improved methodology for evaluating the impacts of water use on life cycle bases. Quicklime production is a high energy consumer that is also characterized by high CO2 emissions. This work sets out to develop the energetic and exergetic balance of the limestone calcination process in order to identify the most influential factors in fuel consumption. The results show that the destruction of exergy during due to the combustion of the fuel and the transfer of heat and moment of the process are the most irreversible processes. The results also show that the energy and the exergy contained in the exhaust gases represent the main loss of the process. The combination of these factors represents more than 50% of the energy supplied to the process.eng
dc.description.abstractEl trabajo trata las metodologías y los indicadores para la evaluación de los impactos de uso del agua dulce, los métodos existentes analizan fundamentalmente la cantidad de agua usada con relación a los impactos ocasionados. Teniendo en cuenta que hay una necesidad reconocida para considerar los impactos, específicamente sobre bases del ciclo de vida, la problemática es que se consideran insuficientes los datos o no son confiables en las bases de datos del ciclo de vida del uso del agua, además no coincide el método de valoración del impacto del ciclo de vida para lo relacionado con los impactos estimados en el uso del agua dulce, se resaltan estas dificultades y se analizan las ventajas, limitaciones, diferencias en los resultados entre diversos métodos y se observa la necesidad de una metodología perfeccionada para la evaluación de los impactos del uso del agua sobre bases del ciclo de vida. La producción de cal viva es un alto consumidor de energía que además se caracteriza por elevadas emisiones de CO2. Este trabajo se propone desarrollar el balance energético y exergético del proceso de calcinación de calizas con el objetivo de identificar los factores más influyentes en el consumo de combustible. Los resultados muestran que la destrucción de exergía durante debido a la combustión del combustible y a la transferencia de calor y momento del proceso son los procesos más irreversibles. Los resultados además muestran que la energía y la exergía contenida en los gases de escape representan la principal pérdida del proceso. La combinación de estos factores representa más del 50% de la energía suministrada al
