ABSTRACT:
Scrubbing solutions containing ammonium salts of weak acids are mixed with sufficient sulfuric acid to react with all the salts; the resultant solutions are evaporated by direct heat exchange with a hot SO.sub.2 -containing combustion gas to a 40-78% water content and combusted at 800.degree.-1,250.degree.C to produce the SO.sub.2 -containing combustion gas used in the evaporation step. The SO.sub.2 in the combustion gas can be processed in a conventional manner.
