The concentration of the sulphuric acid is 90-98% by weight, and the concentration of the concentrated sulphuric acid is 95-98.8% by weight. The air is dried in a dehumidifier. The sulphuric acid can be formed by cooling and condensing of a sulphur trioxide/water containing off-gas thus forming the sulphuric acid. The cooling and condensing can take place in an air cooler, and if an absorption dryer is used, it can be regenerated by warm air being cooling air transferred from the outlet of the air cooler.
