The model proposed by Antonioni et al. (2014) was applied to
assess the performance of both 2S and 1S processes. Given the
input concentration of acid gases, calculated on the basis of different
reference input waste compositions, the consumption of solid
reactants and the production of solid residues needed to remove
acid gases down to a target concentration were quantified. The
model allowed a detailed simulation of the removal process, taking
into account the non-linear relationship between reactant injection
and acid gas abatement, as well as the selectivity of the solid
reactants towards HCl and SO2
