MODELING GAS-LIQUID REACTORS WITH WET PACKING .3. CARBON-DIOXIDE ABSORPTION IN MONOETHANOLAMINE SOLUTIONS

A rigorous mathematical model is developed for the simulation of absorption in a packed column. For the solving of the diffusion and reaction equations around gas-lichid interface was used the orthogonal collocation method and for the integration of the mathematical model equations of the reactor a general computing programe, based on Runge-Kutta method of fourth order, was developed. The solving metods were exemplified by the carbon dioxide absorbtion in monoethanolamine solutions.
