Patent DE-2122634-A1 (DE)
Title: Sulphuric acid prodn - of increased efficiency by charcoal absorption and recovery of residual sulphur oxides
IPC: C01B17/76
Filed: 1971-05-07
Abstract: Gas leaving A H2SO4-absorption tower contg. approx. 0.14% SO2 and 0.03% SO3 is passed into a tower packed with an absorbent, esp. activated charcoal. The absorbent is moistened with water, or alternatively the gases are first passed through a humidifier, so that sufficient moisture is present to convert all the S oxides to H2SO4. When the absorbent is satd. it is washed out with water or acid to product 5-20% aq. H2SO4, and this liquid is fed back into the H2SO4 prodn. system as make-up water for the absorption tower; or, after concn., into the H2SO4 tank of the drying tower. After washing, the absorbent can be dried with air heated by the exchange with the catalytic oxidn. reaction of SO2.
