Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.

A rate-based model of a counter-current reactive absorption process has been developed for the absorption of SO2 into Na2SO3 in a packed column. The model adopts the film theory, includes diffusion and reaction processes, and assumes that thermodynamic equilibrium among the reacting species exists in the bulk liquid. For the calculation of the absorption rate of SO2 into Na2SO3 solution, it is important to take into account all reversible reactions simultaneously. The model was used to calculate concentration profiles in the liquid film, partial pressure, mass transfer rate, pH profiles, enhancement factor along the column. Model predictions were compared to experimental data and a good agreement was achieved. The study provided a basic study for theoretical analysis and engineering design of the process of SO2 absorption in flue gas by sodium alkali solution and other wet FGD process.
