Intensification of Mass Transfer in a Gas–Liquid Apparatus with a Mixer

A new method for dispersing gas from an open vortex cavity into localized zones with reduced pressure in the liquid behind rotating mixer blades is studied. The optimum distance between the blade mixers on the shaft, which ensures the intensification of mass transfer with lower power consumption for mixing, is established. The conditions allowing for an increase in the mass-transfer coefficient are demonstrated and confirmed through numerical simulation. The experimental values of power, gas content, bubble diameter, and mass-transfer coefficient in the apparatus with the mixer implementing the proposed dispersion method are presented.
