Para el diseño conceptual se utilizaron técnicas del análisis de proceso tales como la modelación matemática, la simulación de procesos, la optimización, análisis económico y análisis Pinch entre otras. Se presentan, además, los diagramas de flujo de procesos de ambas alternativas, la validación del modelo matemático empleado para el cálculo del equilibrio vapor - líquido en el sistema agua - ácido nítrico - nitrato de magnesio, así como el dimensionamiento de los equipos principales, optimizando los 2 platos de entrada de la alimentación y del solvente, así como el área de transferencia de calor de los equipos de intercambio térmico. Finalmente se expone un resumen del análisis económico realizado para las dos alternativas estudiadas y la selección de la mejor.]]></p></abstract>

For the conceptual design, process analysis techniques such as mathematical modeling, process simulation, optimization, economic analysis and Pinch analysis were used, among others. The process flow diagrams of both alternatives are also presented, as well as the validation of the mathematical model used to calculate the vapor - liquid balance in the water - nitric acid - magnesium nitrate system, as well as the sizing of the main equipment, optimizing the 2 feed and solvent inlet plates, as well as the heat transfer area of the heat exchange equipment. Finally, a summary of the economic analysis carried out for the two alternatives studied and the selection of the best one is presented.]]></p></abstract>
