A continuation of experiments initiated by Commander Calvin G. Miller, USN, on the effect of flow rate, flow geometry and environment temperature on the effectiveness of a commercial soda lime, Sodasorb, to absorb carbon dioxide from a mixture of carbon dioxide and air is described. Modifications to cylindrical four-inch inside-diameter canisters with three length-to-diameter ratios of 1.225, 1.60 and 2.125 were tested. These modifications were in the form of one-half inch axial spacers or annular rings located within the soda lime bed. Steady flow rates of approximately 1, 2 and 3 SCFM of saturated air at one atmosphere and environment temperatures of 40 deg F, 55 deg F and 70 deg F were used. Temperature and pressure distributions through the soda time bed were measured. The regenerative properties of the soda lime were tested for a length-to-diameter ratio of 2.125, a flow rate of approximately 2 SCFM and an environment temperature of 70 deg F. Author
