  • Sulphuric Acid: Manufacture, Properties, Reactions, Uses

    Sulfuric Dioxide; Manufacturing Process of Sulphuric Acid In general, there are two techniques for industrial production of sulfuric acid They are: Lead chamber process; Contact process; Now, let us look at these processes in detail 1) Contact Process The contact process has three major steps Step – I: Production of Sulphur DioxideSulfuric Acid on large Scale, One being Lead Chamber Process and other Contact Process Lead Chamber Process is the oldest Process Used to manufacture Sulfuric AcidThe main principle behind the process is that the moist Sulphur dioxide in presence of nitrogenous oxides present as Active form of Catalyst is oxidized to sulphur trioxide with theSulfuric Acid Production Using Catalytic OxidationOver the last decades the contact process has been used to produce sulfuric acid, replacing the traditional «Lead Chamber» process dating back to the 18th Century In the contact process SO2 is oxidized to sulfur trioxide (SO3) at high temperature (about 450°C) inSulfuric acid – Manufacturing process of Sulfuric acid
