Gas Dispersion

gdx impellerThe role of the mixer in this application is to increase the gas dispersion throughout the liquid and produce sufficient shear to break the gas bubbles into a size that will give the greatest interfacial area and mass transfer rate. Traditionally, gas is added to the system through a sparge ring or tube mounted just below the mixing impeller. Gas is always introduced to either remove or add something to the liquid. Some examples of gas dispersion applications are air dispersion (oxidation), hydrogenation, and nitrogen stripping. PMSL has the experience and impeller technology to ensure maximum performance is achieved for your process.
