Investigation of Mass Transfer of Ozone in Jet Loop Reactor
Abstract
Mass transfer of ozone in a jet loop reactor was investigated in this study. Diff erent parameters such as ozone gas concentration,
gas fl ow rate, circulation fl ow rate, and spray nozzle diameter were examined for their eff ect on mass transfer. In
experiments with ozone gas concentrations ranging from 3.83 to 17.1 g/m 3 , the K L a values remained unchanged, with an
average of 28.7 ± 2.2 h −1 . As the ozone gas concentration increased, the saturation values of ozone in the liquid phase also
increased. Experiments were carried out with gas fl ow rates ranging from 50 to 250 L/h in the jet loop reactor, and increasing
gas fl ow rates increased the K L a value up to fi ve times. When the eff ect of the liquid circulation fl ow rate was examined for a
spray nozzle diameter of 15.5 mm, increasing the fl ow rate from 40 L/min to 80 L/min increased the K L a value by approximately
41%. However, the power consumed per reactor volume for this process increased 8 times and reached 2.65 kW/m 3 .
K L a values in the JLR vary between 6.1 and 37.3 h −1 depending on operating parameters and it has been concluded that it
performs well compared to its counterparts.
