Liquid phase axial backmixing in the riser and downcomer sections of an airlift loop reactor with non-Newtonian fluids was investigated and determined by dynamic response technique with pulsed tracer input, dual probe detection and computer on-line analysis system under different superficial gas velocity conditions. This method was used to obtain the dispersion coefficient Dz for the individual sections of the reactor. Kolmogoroff's theory of isotropic turbulence was applied to analyse the results of dispersion coefficient. The results show that the axial dispersion coefficient in the riser or downcomer section increases with increasing of superficial gas velocity and apparent viscosity of the fluid. The degree of mixing in the downcomer is higher than that in the riser under the experimental conditions. |
