  • Process for flue gas desulfurization
    Patent number: 4595576
    Abstract: Spent absorbents resulting from desulfurization of flue gas in a spray drying-absorption process contain substantial amounts of sulfite, e.g. calcium sulfite. Said sulfite is oxidized into sulfate by heating of the spent absorbent in the presence of an oxygen-containing gas, preferably at temperatures of 350.degree.-600.degree. C. Thereby the spent absorbents may be converted into materials having industrial utility.
