英文摘要In this experiment, the inert gas is used to agitate two immiscible fluids in microchannels. The mass transfer performances with or without gas agitation are investigated. 30% TBP (in kerosene)-acetic acid-water is chosen as testing system. and nitrogen as agitating gas. The superficial velocities of the immiscible liquid-liquid two phases and gas phase are varied in the range from 0.02 to 1.2 m/s, and 0 to 3.0 m/s. respectively. In microchannels, with enough gas agitating intensity. high dispersion between two immiscible liquid phases can be obtained. The overall volumetric mean mass transfer coefficients are two-folds higher than those without gas agitating, which are in the range of 3.8-30.6 s(-1). Some parameters which impact on the mass transfer process, such as the mixture superficial velocity of the immiscible liquid-liquid two phases, the gas superficial velocity, the microchannel structure, the gas inlet locations and the sampling time are experimentally investigated.
