Title: The Innovations of George L Brownell

Introduction

George L Brownell is a notable inventor based in Monroeville Borough, PA, with a significant contribution to the field of chemical engineering. He holds three patents that showcase his expertise in the removal of carbonyl sulfide from propylene, a critical process in the petrochemical industry. His innovative methods have paved the way for more efficient and effective chemical processing.

Latest Patents

Brownell's latest patents focus on the method of removing carbonyl sulfide (COS) from propylene through hydrolysis over a catalyst comprising platinum sulfide on alumina. In his first patent, he describes a process where propylene is passed through a C3-splitter, a heater, a platinum sulfide catalyst bed, and a topping still. This process effectively separates the resulting hydrogen sulfide (H2S) and carbon dioxide (CO2) from the purified propylene. His second patent further improves this method by regenerating the catalyst through contact with a solvent for polypropylene, ensuring that any polypropylene on the catalyst is readily dissolved. A preferred solvent for this process is liquid propylene, which enhances the efficiency of the catalyst regeneration.
