EN
The characteristic of emulsions generated in the internal loop two-column reactor with mechanical agitation is presented. The phase inversion, circulation velocity and circulation-dependent apparent viscosities of emulsion containing water, paraffin oil and silicon oil are discussed. It is shown that the inversion point can be identified on the basis of emulsion apparent viscosity.
EN
Selected rheological models used for emulsions were verified experimentally and critically discussed. Emulsions were generated in the agitated internal loop coaxial reactor.
EN
Emulsions containing water and paraffin oil are obtained in the internal loop two-column reactor with agitation in the draft-tube as a riser. The continuous water phase circulation velocity increases with an increase of the propeller diameter. Flow of emulsions is similar to the plug flow. The phase inversion is proceeded by the formation of multiple emulsion. Droplet size distributions show a bimodal characteristic. The maxima are observed for several tens nanometers and for a few micrometers of the droplet size,
