industries. However, little attention has been devoted to the
liquid-phase mixing time in gas–liquid-floating particles threephase systems investigated the effects of impeller
type, baffles, gas sparger, rotational speed, gas volumetric flow
rate and particle fraction on mixing time in multi-impeller threephase gas–liquid-floating particle systems by measuring temperature differences using thermocouples. Their work revealed
that the axial flow was the most important factor for the liquid
phase mixing time. Liquid phase mixing time in other three-phase
systems is scarcely investigated, and practically no report on the
mixing time in gas–liquid–liquid agitated reactors has been found
in the open literature, in spite of its importance. The purpose of
this paper is to contribute to the knowledge on the macro-mixing
of the continuous phase in the simultaneous presence of both gas
and oil as dispersed phases, particularly to explore the effect of
aeration and the dispersed oil phase on macro-mixing in the
continuous phase. The mixing time and power consumption in
both liquid–liquid and gas–liquid–liquid systems are measured.
The effects of various operation conditions on the macro-mixing
of liquid phase are analyzed and the mixing time data are
correlated.
