Limestone in flue gas desulphurisation in oxygenenriched atmospheres. Part II: The effect of CO2 on direct limestone sulphation

摘要

The article presents tests carried out on three selected samples of limestone originating from three commercially exploited deposits. The tests of sorbents included desulphurisation in different atmospheres and a physicochemical analysis of desulphurisation products. The aim of the tests was to determine desulphurisation efficiency and conversion degree as dependent on the concentration of O2 and CO2.
