A fundamental description of gas–liquid mass transfer with reversible consecutive reaction has been given. The Film theory has been used and an approximate analytical solution was developed to analyze the isinfo:eu-repo/semantics/othermal absorption. The perturbation analysis technique was used like method of solution of the model equations. Although the model can be adapted to reactions of general stoichiometric and kinetic orders, results have been provided for unit orders only. Predictions of enhancement factors in a liquid film where complex reversible reactions occur were obtained including the presence of external mass transfer resistances in the gas phase. Results have been presented for the case of equal and unequal diffusivities of all the chemical species involved. The approximate results have been compared with exact results available in the literature and a very good agreement was found.
El trabajo de tesis consistirá de un estudio teórico del efecto de las resistencias a la transferencia de masa externas en un proceso de absorción reactiva. En este proceso ocurren simultáneamente transferencia de masa y reacciones químicas en un sistema gas-líquido. El modelado del proceso se efectuará utilizando la teoría de la película y se considerará que las reacciones químicas son reversibles y consecutivas. La solución de las ecuaciones del modelo se realizará empleando técnicas de análisis de perturbación. La hipótesis principal de este trabajo es que los efectos de las resistencias a la transferencia de masa externas influirán significativamente disminuyendo la velocidad de absorción.
