Modeling and Experimental Studies of SO₂ Absorption in Aqueous Ammonia Solution with Wetted-Wall Column

Abstract:

In a wetted-wall column of pilot-scale sulphur dioxide removal efficiencies were measured at 20°C and atmospheric pressure with aqueous ammonia solutions as the scrubbing liquid for different sulphur dioxide inlet concentration in the range of 1000-3000 mg/m³. A mathematical model with the effects of a chemical enhancement factor and sulfite concentration in the liquid phase developed to interpret laboratory experiments was adapted and the calculated values were in reasonable agreement with the experimental values. It appears that this model can provide good predictions of the absorption performances of industrial columns and be helpful to design scrubbers for SO₂ abatement with aqueous ammonia solutions.
