Title: Werner Engelhardt: Innovator in Pickling Solution Regeneration
Introduction
Werner Engelhardt is a notable inventor based in Bendorf, Germany. He has made significant contributions to the field of chemical engineering, particularly in the regeneration of spent pickling solutions. His innovative methods have the potential to enhance efficiency and sustainability in industrial processes.
Latest Patents
Engelhardt holds a patent for a method of regenerating a spent pickling solution. This method involves heating a solution composed of nitric acid and hydrofluoric acid, which contains metal fluorides and metal nitrates, in a reactor at temperatures ranging from 300 to 1,000 degrees Celsius. The process pyrohydrolizes the metal fluorides and nitrates, resulting in the formation of metal oxides that are removed as granulate. Additionally, the gas produced in the fluidized bed reactor is dedusted, cooled, and directed to an acid recovery unit. The spent pickling solution is initially separated into two partial flows: one with free acid and another enriched with metal salts. The free acid flow is sent to the acid recovery unit, while the metal salt flow is processed in the fluidized bed reactor.
