Abstract
The disclosure describes process and apparatus for removing dissolved oxgyen from a liquid wherein the liquid is countercurrently contacted by a sparging gas as the two flow circumferentially through a cylindrical column. The invention applies generally to the achievement of efficient mass transfer between two immiscible fluids of substantially differing density, and is particularly useful as a preparatory step in polymerization processes where a liquid monomer is shipped or stored in an air inhibited condition and the oxygen dissolved must be removed prior to polymerization.
