Title: Innovations of Knut A Andreassen in Magnesium Production
Introduction
Knut A Andreassen is a notable inventor based in Porsgrunn, Norway. He has made significant contributions to the field of magnesium production through his innovative patents. With a total of 3 patents, Andreassen has focused on improving the efficiency and effectiveness of electrolytic processes.
Latest Patents
One of his latest patents is a method and electrolyzer for the production of magnesium. This invention involves the electrolytic production of magnesium from a salt melt comprising magnesium chloride. The electrolyzer features at least one electrolysis compartment and a metal separating compartment, which are separated by a partition wall. The design allows magnesium chloride to be fed in solid form counter to the flow of chlorine gas liberated during electrolysis. This setup ensures that contact between the magnesium chloride and the anodes is avoided, while also facilitating the continuous removal of sludge-forming impurities.
Another significant patent is the development of a replaceable cathode unit. This unit is designed as a module for building stable, non-deformable cathode systems in electrolyzers used for magnesium production via melted salt electrolysis. The cathode unit consists of a straight, longitudinal main cathode with active side surfaces, complemented by two shorter transverse cathodes arranged at right angles. This innovative design enhances the overall efficiency of the electrolytic process.
