New absorbent solutions containing three components have been evaluated for efficiency in decreasing the ambient CO2 level aboard submarines. One of the absorbent systems investigated consisted of a high-boiling organic compound, sulfolane, which has a high physical absorption capacity for CO2, combined with monoethanolamine and water. The other absorbent system has the same components except for the amine, which was 3-aminopropanol. At the same level of saturation of the solutions with CO2, the absorption efficiency of the three-component solutions is about the same as, or slightly inferior to, the corresponding two-component aqueous amines. However, desorption results with the three-component solutions are so much better than for the two-component aqueous amines that the lower CO2 loadings that would be attained in the absorber section of the present CO2 scrubbers should result in significant reduction of the ambient CO2 concentrations in nuclear submarines.
