Title: Quyen C Nguyen: Innovator in Aluminum Processing
Introduction
Quyen C Nguyen is a notable inventor based in Lower Burrell, PA (US). He has made significant contributions to the field of aluminum processing, particularly in the treatment of spent potlining. With a total of 2 patents, his work focuses on improving environmental safety and efficiency in aluminum production.
Latest Patents
Nguyen's latest patents include innovative processes for the stabilization of fluorides in spent potlining. The first patent describes a method for treating spent potlining from the electrolytic smelting of aluminum in cryolite. This process involves incinerating the potlining to combust carbonaceous material, forming an ash at a temperature that maintains low fluorine vapor pressures. By admixing siliceous material with the potlining, either before or after the ash-forming stage, and heating the mixture, a glassy residue is produced. This residue is characterized by low leachability of fluorine in water, making it suitable for landfill disposal.
The second patent also addresses the stabilization of fluorides in spent potlining. It outlines a process that includes burning the spent potlining to form ash, mixing it with siliceous material, and heating to create a residue suitable for landfill. The specified mole ratio of at least about 1.4 silicon to sodium is crucial for the effectiveness of this process. Rapid cooling of the residue further enhances its properties, ensuring low leachability of fluorine in water.
