Title: Fred S. Williams: Innovator in Sodium Oxalate Removal Technologies
Introduction
Fred S. Williams is a notable inventor based in Victoria, TX (US), recognized for his contributions to the field of chemical engineering. He has been awarded 2 patents that focus on innovative methods for enhancing the removal of sodium oxalate from Bayer process liquor. His work has significant implications for the aluminum industry, particularly in improving the efficiency of chemical processes.
Latest Patents
Williams' latest patents include groundbreaking technologies aimed at optimizing the removal of sodium oxalate. One of his patents describes a method where sodium oxalate is precipitated from spent Bayer process liquor by mixing it with a low total alkalinity sodium oxalate seed solution. This solution is treated with two or more adsorbents, such as activated carbon and ESP dust, to effectively remove organic contaminants. Surprisingly, the combination of activated carbon and ESP dust proves to be the most effective, even though ESP dust alone has minimal impact on oxalate removal.
Another significant patent focuses on lowering the organic contaminant content in sodium aluminate solutions. This process involves wet oxidation of organic contaminants in aqueous sodium aluminate solutions, which is enhanced by passing a heated and oxygenated solution through a packed bed containing a chemically inert metal packing member. The process operates at temperatures between 180°C and 300°C, with an oxygen partial pressure of at least 345 kPa.
