摘要：A process and system for production of concentrated sulphuric acid fromsulphuric acid by stripping the sulphuric acid with dried air. The concentration of the

sulphuric acid is 90-98% by weight, and the concentration of the concentrated sulphuricacid is 95-98.8% by weight. The air is dried in a dehumidifier. The sulphuric acid can beformed by cooling and condensing of a sulphur trioxide/water containing off-gas thusforming 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 airtransferred from the outlet of the air cooler.
