Název v původním jazyce

Time evolution of drop size distribution in liquid-liquid dispersion in agitated tank

Popis výsledku v původním jazyce

Agitation of two immiscible liquids or solid-liquid suspension is a frequent operation in chemical and metallurgical industries. Mixing plays a crucial role in these technologies, because it intensifies blending, homogenization, mass transfer and chemical reactions etc. The product quality, yield and economy of the processes is hence significantly affected by mixing. Prediction of mean drop/particle size and drop/particle size distribution (DSD) is vital for emulsification, suspension polymerization, solid particle dispersion or crystallization. Simulation of particulate systems requires the knowledge of DSD and its time evolution. Such description is rare in the literature. We can mostly get information about Sauter mean diameter in the final stage of the process only. Unfortunately, there is a lack of kinetic experimental data to verify the simulation predictions of DSD time evolution. The aim of this contribution is to propose simple semiempirical model for DSD time evolution. The model proposed will be tested on the published and own data. The time evolution of drop size distribution will be measured in a liquid-liquid dispersion in a tank agitated by a Rushton turbine. The drop size will be determined by an image analysis.
