The absorption and subsequent liquid‐phase reaction of oxygen was studied with two types of dispersion apparatus, the Venturi atomizer and the fritted‐glass disperser. The systems studied in both devices included the absorption of atmospheric oxygen by catalyzed sodium sulfite solutions and the simultaneous absorption of atmospheric oxygen with nitrogen dioxide and with sulfur dioxide by water. Very large values of the liquid‐film mass transfer coefficient for oxygen absorption were measured in the atomization zone of the Venturi atomizer. Over‐all recovery efficiencies were less than 2.3% for nitrogen dioxide but reached as much as 22% for sulfur dioxide. Oxidation efficiencies for sodium sulfite solutions ranged up to 80%, depending on the operating conditions. The fritted‐glass disperser gave recovery efficiencies of nitrogen dioxide as high as 90% from air containing 10% of the gas. The recovery efficiency decreased at low concentrations of nitrogen dioxide for both the Venturi atomizer and the fritted‐glass disperser.
