The bisulfate is then pyrolyzed to sulfur dioxide that in turn is converted to sulfuric acid. When this pyrolysis process is combined with the HP0 process, no byproduct ammonium sulfate has to be sold. This supplement presents new process designs for the manufacture of caprolactam by the HP0 route and by the hexahydrobenzoic acid (HBA) routes.
