“…Since carbon dioxide is a major component in waste gases, sulfur dioxide solubility is compared to carbon dioxide solubility in order to examine the solvent selectivity. Luehrs and Godbole (1994) have correlated sulfur dioxide solubilities at atmospheric pressure with solvent parameters. Regarding our field of application (low sulfur dioxide gas concentrations), it is more appropriate to express the solubility in terms of Henry coefficients.…”

It has been found that sulfur dioxide solubility in organic solvents can be well-correlated by Lewis basicity numbers. Mixtures of sulfur dioxide and solvent (N-methylpyrrolidone (NMP), N,N′-(dimethylpropylene)urea (DMPU) and methyldiethanolamine (MDEA)) have been prepared in a 1:1 mole ratio at low temperatures. The melting points of the mixtures are measured, and the mixtures have been analyzed by infrared, ultraviolet-visible, and nuclear magnetic resonance spectroscopy. The solubility of sulfur dioxide has been measured in NMP and DMPU at 25 °C. At sulfur dioxide concentrations of 0.2-0.6 kPa, the solubility is determined using a continuous stirred tank reactor. The absorption of sulfur dioxide proved to be completely reversible. A model where physical and chemical interactions are incorporated showed good correlation with the experimental results.
