Title: The Innovative Contributions of Vivian C. Astley
Introduction
Vivian C. Astley is a notable inventor based in New Orleans, Louisiana, recognized for his significant contributions to the field of chemical engineering. With a total of nine patents to his name, Astley has developed innovative processes that enhance the recovery of valuable materials from various sources. His work has had a profound impact on industries that rely on efficient chemical processes.
Latest Patents
Astley's latest patents include a groundbreaking method for treating spent alkylation acid. This improved process recovers a sulfuric acid product suitable for use in wet process phosphoric plants, particularly those that recover uranium as a byproduct. The method utilizes heat and agitation to polymerize liquid, soluble organic impurities into insoluble, carbonaceous solids. These solids are relatively inert in acidic environments, making them easy to handle while possessing valuable cation exchange and impurity scavenging properties.
Another significant patent involves a process for recovering elemental sulfur from both volcanic and non-volcanic ores. This method includes crushing the ore to a coarse particle size, autoclaving to separate sulfur from the ore, and employing selective grinding techniques to reduce the size of liberated sulfur particles. The process achieves a sulfur purity of at least 99% and recovers over 90% of the elemental sulfur contained in the ore. The efficiency of this process is greatly influenced by the specific crushing and grinding techniques used.
