Resumen
En el presente trabajo se realiza un análisis paramétrico de costos exergéticos al Proceso Linde-Hampson. Se estudia este sistema debido a su alto campo de aplicación, por ejemplo, en el transporte y almacenamiento del gas natural, conservación de alimentos y bebidas o bien en la industria farmacéutica para la conservación de muestras biológicas o de vacunas, etc. Se parte de un análisis termodinámico y se determinan las exergías de cada corriente, las irreversibilidades generadas y la eficiencia exergética en cada equipo. En el análisis de costos exergéticos se implementa la estructura productiva del sistema y, con base a las reglas de asignación de costos [1], se determinan los costos exergéticos y los costos exergéticos unitarios de las corrientes. En el análisis paramétrico, se obtienen los resultados de los costos exergéticos en las condiciones límite del sistema, en este caso, la presión crítica y de inversión a la descarga del compresor. Los resultados muestran que, al variar la presión de descarga entre 346, 200 y 39 bar, se requieren 10.55, 14.15 y 252 kg de aire, respectivamente para producir un kilogramo de gas licuado. El costo exergético es de 8,711.35, 10,587.90 y 130,488.66 kJ, y el costo exergético unitario de 12.18, 14.8 y 182.47 para las presiones de 346, 200 y 39 bar, respectivamente.
In this paper, a parametric analysis of exergetic costs for the Linde-Hampson Process is carried out. This system is studied due to its wide range of applications, for example, in the transportation and storage of natural gas, preservation of food and beverages or in the pharmaceutical industry for the preservation of biological samples or vaccines, etc. Starting from a thermodynamic analysis, the exergies of each stream and the irreversibilities generated in each component are determined. In the exergetic cost analysis, the productive structure of the system is implemented and, based on the cost allocation rules [1], the exergetic costs and unit exergetic costs of the streams are determined. In the parametric analysis, the results of the exergetic costs are analyzed under the system's limit conditions, in this case, the critical and reversal pressure at the compressor discharge. The results show that by varying the discharge pressure between 346, 200, and 39 bar, 10.55, 14.15, and 252 kg of air are required, respectively. The exergetic cost is 8,711.35 kJ, 10,587.90 kJ, and 130,488.66 kJ, and the unit exergetic cost is 12.18, 14.8, and 182.47 for pressures of 200 and 39 bar, respectively.
