Agitated Vessels for Gas-Liquid Dispersion
Agitated vessels for gas-liquid dispersion are specialized mixing systems designed to distribute gas bubbles uniformly throughout liquid volumes for mass transfer, reaction, or flotation processes. These vessels provide efficient gas-liquid contact through optimized sparger design, impeller selection, and operating parameters.
Why are Agitated Vessels Needed for Gas-Liquid Dispersion?
Gas-liquid dispersion requires agitated vessels that break gas streams into small bubbles, distribute bubbles throughout the liquid volume, and maintain adequate residence time for mass transfer. Proper dispersion maximizes gas utilization, enhances reaction rates, and supports efficient aerobic processes.

Agitated Vessels for Gas-Liquid Dispersion FAQs
What impellers provide best gas dispersion?
Rushton turbines are traditional gas dispersers, providing high shear for bubble breakup and good gas hold-up. Concave disc turbines handle higher gas rates with improved flooding resistance. Hydrofoil impellers in upper stages provide bulk circulation. Multi-stage systems optimize both dispersion and circulation.
How do you calculate mass transfer coefficient (kLa)?
Mass transfer coefficient depends on impeller type and speed, gas flow rate, fluid properties, and vessel geometry. We use correlations validated for specific impeller types and verify with CFD modeling. Design targets are confirmed through testing. We guarantee kLa performance for specified conditions.
