摘要:
A process for production of sulphuric acid comprising condensing sulphuric acid vapour from a gas mixture containing 0.01 to 10 vol.% of H 2 SO 4 vapour calculated at complete hydration of SO 3 in the gas to H 2 SO 4 and 0 to 50 vol.% of water vapour by cooling of the gas in a sulphuric acid tower, wherein a stream containing NH 3 is added upstream of the tower in an amount corresponding to 0.01-100 ppm NH 3 by vol. in the gas stream at the entry of the tower.
