Heat Transfer Coefficients in Three – Phase Sparged Reactors: A Unified Correlation

Three – Phase Sparged Reactors are widely used in Chemical, Bio-Chemical and Petrochemical Industrial processes. The advantages of these reactors include high mass and heat transfer rates,isothermal conditions and on-line catalyst addition and withdrawl. The high heat transfer rates of Three-Phase Sparged Reactors are particularly attractive for highly exothermic reactions where substantial reduction in heat transfer surface can lead to lower reactor cost . In the present paper mainly , the studies on heat transfer coefficients in slurry bubble columns and threephase fluidized beds are examined . The author data is compared with the unified correlation of Suh and Deckwer [19] and important conclusions are drawn. The development of author’s unified correlation of heat transfer coefficients in ThreePhase Sparged Reactors are presented.
