    摘要: A SYSTEM FOR REDUCING THE CORROSION RATE ON METALS IN A SPENT SULFURIC ACID SLUDGE ECOVERY POCESS. THIS SYSTEM COMPRISES THE ADDITION OF A CORROSION INHIBITOR TO SPENT SULFURIC ACID SLUDGES, AS IT IS PUMPED FROM A STORAGE MEDIUM THROUGH A HEAT EXCHANGER TO MAINTAIN THESE SLUDGES AT A CONSTANT TEMPERATURE. THE CORROSION INHIBITORS CONSIST OF WATER OR WATER IN THE FORM OF DILUTE FRESH SULFURIC ACID.
