Abstract
Rotating disc reactor (RDR) was constructed to conduct gas–liquid–solid reactions with controlled reagent transfer from gaseous to liquid phase. The concept is based on continuous formation of thin liquid films at a surface of rotating discs where the mass transfer proceed in diffusion–convective way.
The reactor was employed to run precipitation reaction of CaCO3 via carbon dioxide absorption in lime slurry. During each reaction pH changes and Ca2+ concentration in time were measured. Disc rotations and gas flows were changed during the experiment and their influence on the obtained CaCO3 powders has been examined and fully discussed.
