Hydrodynamic Characteristics in Internal Air Lift Loop Reactor
Hydrodynamics is an important issue for the design and development of three phase internal air lift loop reactor. This paper deals with the experimental investigations on the effect of superficial gas velocity within the range 0.01-0.1m/secand50Kg/m concentrations of solid,solid density (853.5 Kg/...

| description | Hydrodynamics is an important issue for the design and development of three phase internal air
lift loop reactor. This paper deals with the experimental investigations on the effect of superficial gas
velocity within the range 0.01-0.1m/secand50Kg/m concentrations of solid,solid density (853.5 Kg/m ) on the 3 3 riser gas holdup, mass transfer coefficient and circulation time of a gas-liquid-solid internal airlift loop reactor and it was characterized using Newtonian and non Newtonian systems. Air-water, air-50% glycerol solution,
air-10%ethanol solution and air-10%methanol solution are used as Newtonian liquids and air-2% carboxyl
methyl cellulose solution (CMC) is used as a non Newtonian liquid. Polyethylene-non-porous-solid particles
were used as solid phase. The phase flow rates and concentration of solid particle had a significant effect on
the hydrodynamic characteristics ofthe internal air lift loop reactor such as riser gas holdup ( ), mass transfer g
coefficient (Kla) and circulation time (Tc). From experimental observations g La and K increased with increasing gas velocity, while Tc decreases with increasing gas velocity |
