LIQUID PHASE MIXING IN THE GAS-LIQUID JET REACTOR WITH LIQUID JET EJECTOR

Abstract

The liquid-phase mixing pattern and dispersion coefficients were studied by the tracer concentration distribution at steady state and the impulse response method for the gas-liquid jet reactor with liquid jet ejector.
The longitudinal liquid-phase mixing pattern was quite different between the spouting section and the calm section. In the spouting section, which was the lower region in the column, the liquid phase was regarded as almost completely mixed flow. By contrast, in the calm section, which was the upper region, the value of the dispersion coefficient was fairly smaller than that in bubble columns and back-mixing of the liquid phase was suppressed.
