Abstract
A gas-liquid mixing system employs an impeller/draft tube assembly submerged in liquid. Hollow eductor tubes affixed to the impeller drive shaft are used to flow gas from an overhead gas space to the liquid in the vicinity of the assembly. The positioning and size of the eductor tubes are such as to maximize the desired gas-liquid mixing and reaction rate.
