The report reviews the work of H. F. Johnstone in 1935 and of B. A. Chertkov in the 1950's, related to laboratory vapor pressure-temperature measurements of sulfur dioxide, ammonia, and water above ammoniacal solutions. It indicates that, although Johnstone and Chertkov are in general agreement, their measurements lead to different conclusions in several instances. The report suggests resolutions of the differences noted: the relationship recommended should provide a reliable basis for designing ammoniacal scrubbers for removing sulfur oxides from waste gas. As for other absorbents, design data for ammoniacal scrubbers must include detailed knowledge of solution properties. Ammonium sulfite and bisulfite are far more soluble in water than other sulfites. This constitutes an important scrubber credit that has prompted careful study of ammoniacal solutions.
