Abstract
The article presents the possibility of using calcareous wastes to produce alternative sorbents for flue gas desulphurization. Calcareous wastes from chemical plants produced during the propylene oxide production process were used. In order to assess the potential of stored waste, they were subjected to comprehensive physical and chemical tests: the chemical, morphological, structural, fractional composition and reactivity were determined. Due to the nature of its formation, lime waste was subjected to electromagnetic activation to improve its sorption properties. The impact of activation on physico-chemical properties was also determined. The verification of the tests carried out on a micro scale was the flue gas desulphurisation test performed on a real object using the activation technology in an electromagnetic mill. The aim of the test was to obtain similar results of flue gas desulphurisation with the use of a waste sorbent for the lime milk used in this method.
