Sažetak
In modelling of spray scrubbers used for flue gas desulfurisation, absorption in liquid wall films is generally disregarded, as insufficient data and numerical models are present in literature. Furthermore, no exact data is available for determining the importance of the wall film in the overall absorbing process. Present work parametrically analyses different models for mass transfer in wetted walls and compares them to the available experimental data. Additionally, the wall film absorption model is included in a previously implemented computational fluid dynamics model for sulfur dioxide absorption. Results indicate that the degree of wall film absorption depends on operating parameters such as temperature, liquid-to-gas ratio, spray configuration, and scrubber geometry, but the wall film can contribute up to 6 % of the overall absorption. Therefore, to model the absorption in spray scrubbers as accurately as possible, wall film phenomena cannot be disregarded.
