The deagglomeration of titanium-dioxide powder in water suspension performed a stirring tank was investigated. Owing to the widespread applications process and titanium dioxide powder, new, more efficient devices methods predicting result are highly needed. A brief literature review application process, device used, mechanism is presented herein. In experiments, performed. change particle size ...

In this study, liquid-liquid extraction process in a Kuhni extraction column was modeled and simulated. A non-equilibrium dynamic model was developed for modeling liquid-liquid extraction processes based on a rate-based model. The model equations are inclusive of partial and ordinary differential equations which were discretized in column height direction. The population balance model was used ...

Energy sector is considered to be one of the most important components of a country's infrastructure and a key indicator of the standard of living. Energy consumption reflects upon population growth, living standard, and the level of development in all aspects of life. It is of utmost importance to study the current situation of energy consumption for developing energy plans and policies and to...

We consider several structured population models (age structured, size structured, maturity structured) and the general scattering equation. These models are not conservation laws, nevertheless we show that they admit a common relative entropy structure which uses the first eigenelements of the problem. In case of scattering, it is more general than the usual ”detailed balance principle”. Three...
