Title: Walter A. Braunlin: Innovator in Coal-Oil Slurry Heating Processes
Introduction
Walter A. Braunlin is a notable inventor based in Spring, TX (US). He has made significant contributions to the field of coal processing, particularly through his innovative patent related to heating coal-oil slurries. His work has implications for improving efficiency in coal liquefaction processes.
Latest Patents
Walter A. Braunlin holds a patent for a process that focuses on heating coal-oil slurries. This process involves controlling the gas to slurry volume ratio to achieve a gas holdup of about 0.4 when heating a flowing coal-oil slurry and a hydrogen-containing gas stream. This innovation allows for operation with virtually any coal to solvent ratio, facilitating efficient heat transfer and satisfactory pressure drops. The critical minimum gas flow rate for any given coal-oil slurry is influenced by various factors, including coal concentration, particle size distribution, and the composition of the solvent. Furthermore, the system's efficiency can be enhanced by utilizing multiple heating zones to provide high heat flux when the apparent viscosity of the gas-saturated slurry is at its peak.
Career Highlights
Walter A. Braunlin is associated with the Pittsburg & Midway Coal Mining Company, where he has applied his expertise in coal processing. His patent demonstrates a deep understanding of the complexities involved in coal liquefaction preheating, where the coal-oil slurry and hydrogen-containing gas stream behave as a Newtonian fluid under specific conditions. His work has contributed to stable operations, achieving a maximum gas holdup of up to 0.72.
