Abstract: Pure concentrated H2SO4 is prepared by introducing gaseous SO2 and water into the lower and upper parts respectively of a column, the central portion of which contains packing, whereby a layer of boiling 97-98.3% H2SO4 is formed in the central portion; and removing part of the reaction heat by supplying excess water, allowing excess to vapourize, condense at the top of the column, and be returned to the boiling H2SO4. The remaining reaction heat is removed by product H2SO4, which is passed through a de-aerator and cooler. Temperatures of 320-333 DEG C. can be maintained under normal pressure. Up to 10% of an inert gas, e.g. air or N2, may be mixed with the SO3, and escapes at the top of the column with any SO2. Parts of the column which come into contact with H2SO4 are made of, or lined with, quartz or noble metals.
