Estudio de simulación de la eliminación de CR (VI) en aguas residualess
.
Sumario:
La adsorción es una técnica de superficie que es empleada para remover contaminantes como los metales pesados utilizando materiales orgánicos como bioadsorbentes. La mayoría de los estudios realizados de adsorción se han llevado a cabo a nivel de laboratorio por lo cual son muy pocos los estudios realizados que buscan predecir el comportamiento del proceso y la eficacia del adsorbente a nivel industrial. Por lo tanto, el objetivo del presente estudio es utilizar herramientas computacionales para modelar una columna de adsorción empacada a escala industrial para remover Cr (VI) en solución aprovechando la biomasa a base de Theobroma cacao L como material adsorbente. Para ello, se utilizó el software Aspen Adsorption para realizar varias simu... Ver más

Most of the adsorption studies have been carried out at the laboratory level, so there are very few studies that seek to predict the behavior of the process and the efficiency of the adsorbent at the industrial level. Therefore, the objective of the present study is to use computational tools to model an adsorption column packed at industrial scale to remove Cr (VI) in solution using Theobroma cacao L biomass as adsorbent material. For this purpose, Aspen Adsorption software was used to perform several simulations of an industrial scale adsorption column with different configurations to obtain a parametric evaluation using the Langmuir and Freundlich isothermal models with the Linear Global Resistance (LDF) kinetic model. The results obtained show that the Langmuir-LDF model presented adsorption efficiencies up to 96% while the Freundlich-LDF model up to 97%. On the other hand, the adsorption column simulation conditions that presented the best results for both cases were a column height of 4 m, initial Cr (VI) concentration of 2000 mg/L, and an inlet flow rate of 100 m3/day. This study is presented as a novel way in the engineering field on how computational tools have the ability to predict the possible behavior of adsorption columns packed with organic waste-based biomasses.
