Notes:
By means of gas-absorption experiments in a stirred vessel, with various depths of liquid above a properly positioned single-opening pipe-type gas sparger, conclusions are reached about relative contributions to the overall absorption rate by localized actions near the sparger tip, in the impeller region, and from bubbles distributed in the bulk volume of the fluid. Results are discussed for difficulty soluble gases (oxygen in water and chlorine in water) and a substantially soluble gas (chlorine in benzene). In all cases, dissolution rates in the vicinity of the sparger and impeller were significantly large compared with those near free bubbles.
