Title: Innovations by George K. Tyson
Introduction
George K. Tyson is an accomplished inventor based in Walnut Creek, CA (US). He has made significant contributions to the field of chemical engineering, particularly in the area of fluoride removal and recovery processes. With a total of 2 patents, his work has had a notable impact on industrial applications.
Latest Patents
One of Tyson's latest patents focuses on the removal of potassium fluoride from potassium chloride. This innovative process improves the removal of fluoride ions by adjusting the pH of the aqueous solution used in fractional crystallization. By maintaining the pH between about 6 and 9, the fluoride ion contamination of potassium chloride can be significantly reduced, as demonstrated by a reduction from 1000 ppm to 90 ppm at a pH of 6.5.
Another important patent involves the recovery of ammonia and fluoride values from ammonium fluoride solutions. In this process, potassium hydroxide is added to the aqueous solution, allowing for the distillation of ammonia. The remaining solution is then concentrated and combined with a dipolar aprotic solvent, such as N-methylpyrrolidone, to obtain potassium fluoride as a slurry. This slurry is particularly useful in replacing chloride in heterocyclic and aryl chlorides with fluoride.
