What is A Film-penetration Model for Non-isothermal Absorption with Chemical Reaction about?

A model for non-isothermal absorption with chemical reaction based on Toor and Marchello's "lm-penetration concept was developed for "rst-and second-order irreversible reactions. Enhancement factor predictions are discussed in terms of the gas reactant solubility, reaction activation energy, solution and reaction heats, reactant concentrations and di!usivities. Results are compared with those of non-isothermal "lm and penetration models. For "rst-and second-order reactions, the predictions of non-isothermal "lm-penetration model di!er from both non-isothermal "lm and penetration results, but are closer to the former. Also, predictions for non-isothermal "lm-penetration model are similar to the corresponding isothermal ones when the process is limited by liquid-phase reactant. Results of non-isothermal "lm-penetration model presented here provide quantitative support to the long used assumption that the "lm theory results represent conservative estimates for most systems.
