The principles of mass and heat transfer for non-isothermal gas absorption with chemical reaction have been applied to the derivation of a mathematical model describing the complexing of carbon monoxide with aluminum cuprous tetrachloride in toluene and the absorption of carbon dioxide with aqueous monoethanolamine

both in packed columns. The fundamental differential equations of the process were treated with the fourth-order Runge-Kutta method

leading to the establishment of the temperature and concentration profiles for both the gas and liquid phases along the packed height. The results conform reasonably well with pilot plant data.
