Mathematical Modeling of SO₂ Absorption in a Venturi Scrubber

Abstract

Abstract A three-dimensional mathematical model was used to predict the removal efficiency of a venturi scrubber for SO2 absorption into a water and alkaline solution. In order to obtain better results, nonuniform droplet concentration distribution was considered. The results of the model with nonuniform droplet concentration distribution are compared with several sets of experimental data, as well as with prediction data of a mathematical model with uniform droplet concentration distribution. Without exception, all comparisons indicated that including nonuniformity of droplet concentration distribution in the model will significantly improve the agreement between the experimental data and predicted values.
