Additionally, the hydraulic behavior was studied and the efficiency of some trays in different points of column was estimated by CFD. To achieve that, five specific objectives were established: 1) Select the most suitable type of concentric HIDiC configuration for the separation of the propylene-propane mixture, considering second thermodynamic law, as well as the effect of the configuration on the entropy generation, the energy and exergy required for the separation. 2) Fit a CFD model for predicting the hydraulic behavior and mass transfer efficiency in a tray of the selected HIDiC. 3) Identify effects of column design and operating variables on thermal, hydraulic and mass transfer performance in a HIDiC tray. 4) Analyze the second law efficiency in the selected HIDiC, distinguishing the exergetic losses by phenomena, and 5) Propose a preliminary methodology for the conceptual design of concentric HIDiCs, considering the operational viability and its thermodynamic efficiency. In the development of the first objective, it was possible to determine that the HIDiC column that presents the best exergetic behavior, for the separation of the studied system, is the Top-HIDiC (Chapter 1). In the second objective, due to the absence of experimental data for the chosen system, we first proceeded to validate the use of CFD for a known binary system with experimental data of its hydrodynamic behavior (Chapter 2), and mass transfer, through tray efficiency (Chapter 3). Once the hydrodynamic and mass transfer components were validated, the CFD was applied to a tray of the HIDiC for the propylene-propane system (Chapter 4), predicting the clear liquid height and the tray efficiency in rectification and stripping sections, obtained results were coherent with the studied phenomenon. For the third objective (Chapter4), three integrated trays ‒located in different places of the HIDiC: above, in the middle and in the lower‒ were analyzed to check the influence of initial and boundary conditions on the studied properties (clear liquid height and tray efficiency). For the fourth objective, it was possible to discriminate the exergetic losses for each component of the HIDiC column and they were compared with the losses generated in a Conventional Column and a Vapor Recompression Column, confirming a higher thermodynamic performance for the HIDiC (Chapter 5). Finally, in the development of the last objective, it was possible to establish a preliminary conceptual design through 5 general steps, with the exergetic loss as the main design criteria (Chapter 6). (Texto tomado de la fuente)En este estudio se analizó el desempeño termodinámico de una columna de destilación concéntrica, con integración energética interna, para separar la mezcla propileno-propano, mediante el análisis de segunda ley de la columna. Adicional, se estudió el comportamiento hidráulico y se determinó la eficiencia de un plato en diferentes secciones de este tipo de columnas mediante CFD. Para lograr esto, se establecieron cinco objetivos específicos: 1) Seleccionar del tipo de configuración HIDiC concéntrica más adecuado para la separación de la mezcla propileno-propano mediante el análisis de segunda ley de la termodinámica aplicado en la columna completa considerando el efecto de la configuración sobre la entropía generada, la energía y exergía requerida para la separación. 2) Predecir el comportamiento hidráulico y la eficiencia de transferencia de masa en un plato de la HIDiC seleccionada usando CFD. 3) Identificar efectos de las variables de diseño y de operación de la columna sobre el desempeño térmico, hidráulico y de transferencia de masa en un plato de la columna HIDiC. 4) Analizar la eficiencia de segunda ley en la HIDiC seleccionada considerando las pérdidas exergéticas generadas por cada uno de los fenómenos, y 5) Proponer una metodología preliminar para el diseño conceptual de columnas HIDiC concéntricas, considerando la viabilidad operacional y su eficiencia termodinámica. En el desarrollo del primer objetivo, se logró determinar que la columna HIDiC que presenta mejores resultados exergéticos (segunda ley), para la separación del sistema de estudio, fue la HIDiC de tope (Capítulo 1). En el segundo objetivo, debido a la ausencia de datos experimentales del sistema en este tipo de columnas, se procedió primeramente a validar el uso de CFD para el caso de un sistema binario conocido que contara con datos experimentales tanto en la parte hidrodinámica mediante la propiedad altura del líquido claro (Capítulo 2), como de transferencia de masa mediante la eficiencia de plato (Capítulo 3) obteniéndose resultados muy cercanos a los experimentales; éstas simulaciones se realizaron sobre un plato perforado rectangular. Una vez validado la parte hidrodinámica y de transferencia de masa, se procedió a aplicar el CFD a una sección de plato de la columna HIDiC (Capítulo 4), prediciendo la altura del líquido claro y la eficiencia de plato, en ambas secciones, rectificación y agotamiento, obteniéndose resultados coherentes con los fenómenos estudiados. Para dar cumplimento al objetivo tres, se tomaron tres platos integrados ubicados en diferentes lugares de la columna HIDiC, uno arriba, otro en el medio y otro en la parte de debajo de la columna las cuales contaban con tres condiciones diferentes (Capítulo 4) comprobando la influencia de estas condiciones iniciales y de frontera sobre las propiedades estudiadas (altura del líquido claro y eficiencia de plato). En el cuarto objetivo se logró discriminar las perdidas exergéticas por cada componente de la columna HIDiC y se compararon con las pérdidas generadas con la columna convencional y la de recompresión de vapor obteniéndose mejores resultados en la columna HIDiC (Capítulo 5). Para finalizar, en el desarrollo del último objetivo, se logró establecer un diseño conceptual preliminar mediante 5 pasos generales teniendo como base principal del diseño el principio de pérdida exergética (Capítulo 6).Colciencias - Beca 617DoctoradoDoctor en Ingeniería Químicaxxvi, 164 páginasapplication/pdfengUniversidad Nacional de ColombiaBogotá - Ingeniería - Doctorado en Ingeniería - Ingeniería QuímicaFacultad de IngenieríaBogotá, ColombiaUniversidad Nacional de Colombia - Sede BogotáAnalysis of a depropanizer column with internal energy integration of concentric configurationAnálisis de una columna depropanizadora con integración energética interna de configuración concéntricaTrabajo de grado - Doctoradoinfo:eu-repo/semantics/doctoralThesisinfo:eu-repo/semantics/acceptedVersionhttp://purl.org/coar/resource_type/c_db06Texthttp://purl.org/redcol/resource_type/TDBejan, A.
