Latest Patents

Frank Bärhold holds a patent for a method of regenerating a spent pickling solution composed of nitric acid and hydrofluoric acid, which contains metal fluorides and metal nitrates. In this method, the pickling solution is heated in a reactor to about 300-1,000 °C. The metal fluorides and metal nitrates undergo pyrohydrolysis, resulting in the formation of metal oxides, which are then removed as granulate. The gas produced in the fluidized bed reactor is dedusted, cooled, and directed to an acid recovery unit. Initially, the spent pickling solution is separated into a partial flow with free acid and another partial flow enriched with metal salts. The partial flow enriched with free acid is sent to the acid recovery unit, while the flow enriched with metal salts is processed in the fluidized bed reactor.
