Latest Patents
One of Careatti's latest patents is focused on "Alumina distribution in electrolysis cells including inert anodes using bubble-driven bath circulation." This invention relates to the use of bubble-driven flow to enhance the dissolution and distribution of alumina in an aluminum electrolysis cell operating with inert anodes. By harnessing the driving force of bubbles rising along the sides of a sloped anode to induce circulation in a cell, alumina distribution can be maintained close to or at saturation without the formation of muck or sludge. This innovative approach allows alumina fed through point feeders at specific locations to be distributed throughout the entire cell rather than sinking to the bottom below the feed location. For a given circulation pattern, feeder locations can be optimized for better performance.
Another significant patent by Careatti is the "Chemical milling process for inert anodes." This patent discloses a cermet inert anode with a reduced level of contaminating surface metal. The methods for preparing and treating cermet inert anodes generally use an oxidizing agent to convert metals on the surface of the anode to inert oxides and/or to remove metal contaminants. The inert anodes developed through this process may be utilized in electrolytic reduction cells for the production of commercial purity aluminum, as well as other metals.
