Abstract
The authors describe process technology for processing acid tars to obtain sulfuric acid by means of high temperature splitting to regenerate spent sulfuric acid contaminated with organic impurities. An illustration presents a simplified flow plan for acid tar processing. The authors conclude, from experience with this unit, that process indexes meet design requirements, in particular with respect to the degree of decomposition of the acid tar, the temperature conditions the SO/sub 2/ conversion, the SO/sub 3/ adsorption, and the quality and quantity of the oleum and commercial sulfuric acid obtained.
