Gas dispersion applications include:
BIO-oxidation processes (Bacterial Leaching)
Fermentation and Hydrogenation
In these processes, large volumes of gas are injected into the vessel/reactor – through some type of dispersion unit, be it a sparge ring or pipe. Impellers for these applications need to be carefully selected to prevent flooding of the impeller, by the air, and to ensure effective dispersion, blending and solids suspension.The mechanical design of these systems is often complex, with the agitators “seeing” large fluid forces and consequential shaft deflection. AFROMIX have extensive experience in the process and mechanical design of these agitators.The impeller of choice is the AFROMIX high solidity P4 impeller, providing efficient operation at high gas induction rates.
