摘要：The invention provides a process and system for production of concentratedsulphuric acid from sulphuric acid by stripping the sulphuric acid with dried air. Theconcentration 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. Thesulphuric acid can be formed by cooling and condensing of a sulphur trioxide/watercontaining off-gas thus forming the sulphuric acid. The cooling and condensing can takeplace in an air cooler, and if an absorption dryer is used, it can be regenerated by warmair being cooling air transferred from the outlet of the air cooler.
