Title: Michael George Willis: Innovator in Alumina Production
Introduction
Michael George Willis is a notable inventor based in Arvida, CA. He has made significant contributions to the field of alumina production, particularly through his innovative patent that addresses the control of sodium oxalate levels in the Bayer process.
Latest Patents
Willis holds a patent for the "Production of alumina." This invention involves a method to control the sodium oxalate level in the liquor used in the Bayer process. The process entails concentrating a portion of the spent liquor recovered from the alumina trihydrate precipitation stage by evaporation. This concentration renders the liquor supersaturated with respect to sodium oxalate. The concentrated liquor is then sprayed onto a packing in an enclosed space, where the conditions ensure that the supersaturation of the droplets at impact exceeds a critical level. This innovative approach allows for the deposition of sodium oxalate on the packing, which is subsequently recovered for recirculation in the process circuit.
