Simulation of packed gas absorption columns with first order irreversible reactions

Gas absorption in packed towers has been modelled taking into account heat effects and first order irreversible chemical reactions. A theory based on the film factor concept was developed using steady state assumptions. The theory was transformed into a computer program which simulates the start-up procedure of the column dynamically and shows good convergence behavior. The computer program was tested with a pseudo-first order case, NaOH-CO2-Air, and good agreement with experimental data [21] was obtained.
