Summary on Grant Application Form |
|
One of several possible operating modes for gas-liquid-solid systems makes use of the air-lift principle (extensively studied for two phase systems in connection with fermentation technology). This principle is based on creating a distinct zone within the reactor through which gas rises; this in turn creates a density difference between the gas-liquid-solid zone and the liquidsolid zone; this density difference induces circulation of the liquid and solid phases through both zones (Figure 1). This circulation creates good mixing in all three phases; good mass transfer; even distribution of the solids throughout the reactor; and efficient suspension of solids in the liquid. Surprisingly, the hydrodynamics of these reactors has been little studied and is poorly understood. There is no useful basis for estimating the liquid recirculation rate or the degree of solids suspension as a function of reactor geometry and gas flowrate. This project is aimed at redressing our meagre knowledge of the fundamental hydrodynamic behaviour of these systems, and providing a basis for the engineer to approach the design of a three phase air lift (TPAL) reactor.
