ABSTRACT:
A mixing system for dispersing gas or other fluids in liquid which may have a solid suspension so as to improve mass transfer to the liquid or its solids suspension while maintaining a low pattern which is substantially axial (up and down) in the tank containing the liquid thereby also facilitating mixing (blending) utilizes an (unshrouded) axial flow impeller which provides the desired single stage axial flow downwardly to the bottom of the tank and upwardly along the sidewalls of the tank with radial flow confined principally to the bottom region of the tank. A sparge system which releases the gas or other fluid in the region at the bottom of the tank where the flow is predominantly radial allows attainment of gas rates with complete dispersion of gas throughout the tank which rates are much higher (about four times as great) as when conventional sparge systems are used with axial flow impellers.
