RESUMO

The objectives of this work are the modeling and the simulation of a plate, multicomponent absorption column, considering the main phenomena taking place in the process and the rigorous thermodynamic of phase equilibria. The problem is considered in the steady-state and adiabatically. A method initially developed for distillation columns is now applied for absorption columns. The solution of the non linear system of equations is carried out by the Newton-Raphson Method. A software made by four programs is developed in such way to allow an interactive simulation, where the necessary parameter alteration for the calculations is made simultaneously and immediately. The interactive procedure allows suitable choice of the operating conditions and, therefore, allows for optimized solutions. The results of the simulations were near to the ones obtained by the commercial simulator ASPEN, what was important for the model validation. " Operation under high pressure has larger efficiency, the same with low temperature for solvent feed and solvent with higher molecular weight. Finally, in this work, it was carried out a simulation of an absorption process using water as the solvent from a gaseous stream of an incinerator of hazardous waste. This is very important for waste minimization considerations, in particular, in this case, related to the HC1 emission
