The improvement potential of fluorosulfuric regeneration in the acid polishing process of the lead crystal glass industry is demonstrated by serveral model calculations. As main advantage a remarkable decrease in waste acid production and the connected neutralization expenses can be expected. The successful change of a two-bath acid polishing plant from conventional acid regeneration to HSO3F regeneration is described.
