Title: Bruce B Doll: Innovator in Catalyst Recovery Methods
Introduction
Bruce B Doll is a notable inventor based in Decatur, AL (US). He has made significant contributions to the field of chemical engineering, particularly in catalyst recovery methods. With a total of 2 patents to his name, Doll's work has had a meaningful impact on industrial processes.
Latest Patents
One of Doll's latest patents is a catalyst-recovery method designed for catalysts used in a continuous liquid phase oxidation process. This method focuses on converting an aromatic alkyl into an aromatic carboxylic acid product. The process involves withdrawing the aromatic carboxylic acid product from an oxidation reactor as an aqueous product, which is then subjected to crystallization. This results in the production of the aromatic carboxylic acid product and a product mother liquor stream. The mother liquor stream is subsequently separated into a solvent-rich stream and a solids-containing catalyst-rich stream. The catalyst-rich stream is further processed to yield a by-product cake and a catalyst-bearing stream that is substantially free of solids. A portion of this catalyst-bearing stream is then contacted with the vapor stream in the absorber system, leading to the withdrawal of a catalyst-rich bottoms stream. Finally, a portion of this bottoms stream is returned to the reactor, enhancing the efficiency of the process.
