Abstract

Technical grade fluorosulfuric acid (HSO3F) has been commercially available since several years. Earlier problems with transportation, storage and supply equipments are no more restrictions for the use of HSO3F in industrial processes. The improvement potential of fluorosulfuric regeneration in the acid polishing process of the lead crystal glass industry is demonstrated by several 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.
