The key point of the methodology is the application of the acid
gas conversion model, tuned on actual operational data (Antonioni
et al., 2014), which links the removal efficiency of the system to the
actual ratio of reactant feed to acid pollutants load in the flue gas.
This approach allows avoiding the use of fixed generic values of
reactant feed rate per mass unit of waste, which are usually introduced
in life cycle studies of air pollution control lines (Scipioni
et al., 2009; Damgaard et al., 2010). Thus, the selectivity of the different
solid reactants towards HCl and SO2 is correctly taken into
account.
