Influence of the Gas Inlet Temperature

The parameters of the experiments for the variation of the gas inlet temperature are displayed in Tabs. 16.5-16.8. 

Although the temperature of the liquid film changes by 10 K due to an increased inlet temperature from 100 °C to approx. 190 °C, the effect of increased solubility of sulfur dioxide (Fig. 16.22) or calcium hydroxide on the conversion plays an insignificant role. 

The thermodynamic model of Krissmann [53] was used in the calculations of these experiments, though this was limited by the phase equilibrium (Eq. (3)) and the reaction equilibrium (Eq. (4)). Calculation of the activity coefficients of the H+ ions and HSOj was performed according to the extended Debye-Hiickel theory, using the approximation of Pitzer 

The reference condition of the ideal diluted solution and the ion strength Ix is approximated with the mass content 

The activity coefficient of the molecular diluted sulfur dioxide is set to 1. The water
