  • Method for inhibiting corrosion in integrated spray drying-calcining process
    Patent number: 4883004
    Abstract: Corrosion and sulfuric acid formation in an integrated spray-drying and calcining operation is inhibited by operating the calciner at a temperature so that the exit gases from the calciner provides sufficient heat to the spray drier to keep the exit gases from the spray drier at a temperature above the dew point of the SO.sub.3 /H.sub.2 O vapors present in the spray drier exit gas.
