Experimental study of a cocurrent upflow packed bed bubble column reactor: Pressure drop, holdup and interfacial area

Eugeniusz Molga , K. Roel Westerterp

Abstract

Gas-liquid interfacial areas have been determined by means of chemically enhanced absorption of CO2 into DEA in a packed bed bubble column reactor with an inner diameter of 156 mm. The influence of the gas velocity and particle diameter on the interfacial areas, pressure drops and liquid holdups has been investigated. For both packings the limiting values of the gas velocities have been determined above which the interfacial areas and liquid holdups stabilize. In particular gas channelling has been found, which is less pronounced in the bed of larger particles. © 1997 Elsevier Science S.A.
