I’m seeking help from experts. Our factory concentrates and purifies 72% sulfuric acid to 95% purity. The flow rate of this 72% acid is around 1.2 tons per hour; it is fed into the tower from the top, with the temperature of the reactor at 320°C and the temperature at the top of the tower around 145°C. How much mixture of sulfur trioxide and sulfur dioxide can be produced per hour?

OP, what process was used to produce your sulfuric acid? It seems to be similar to acid derived from dried chlorine, and its concentration is quite high. Also, are there many impurities in the waste acid?
