| Abstract |
Waste sulfuric acid is generated as a result of refining n-paraffins and/or other hydrocarbons with oleum. The VEB Leuna-work have developed a process for reprocessing waste sulfuric acid. Sulfuric acid is recovered through (1) high-temperature thermal decomposition, whereby SO2-containing flue gases are generated and (2) the absorption of the SO2 by means of ammoniacal sulphite-bisulphite solution. The ammonium bisulphite (ammonium hydrogen sulphite) thus generated can be used in the manufacture of caprolactam or in the pulp industry for the digestion of cellulose. |
