Abstrakt

In the paper, the analysis of the chosen parameters effects (gas flow rate, the impeller speed, type of impeller and concentration of the aqueous solutions of sucrose) on the gas hold-up for gas-liquid and gas-liquid--biophase systems mechanically agitated are presented. Experimental studies were conducted in a vessel of the diameter of 0.288 m. The agitated vessel was equipped with Rushton or A 315 impeller. The results were described mathematically. The study shows that gas hold-up strongly depends on the impeller speed and the gas flow rate.
