Abstract: Process for the production of concentrated sulphuric acid and oleum from feed gases with up to 70% SO2+SO3 (SOx) and a content of H2O corresponding to H2O/SO3 molar ratios up to 1.6, particularly in the range of 0.5 to 1.6 upstream an intermediate sulphuric acid condenser comprising an air recycling loop with water addition. The process of the invention minimizes power consumption of the sulphuric acid plant by reducing the consumption of cooling water and obtaining maximum possible recovery of the heat liberated in the process for production of high pressure steam for power production. Up to 99.95% of the SOx in the feed gas can be recovered as typically 98.5-99.5 wt % concentrated sulphuric acid and/or oleum with up to 25 wt % SO3.
