Data on the solubility of acid and hydrocarbon gases for poly(glycol ethers) are necessary for the development of the University of California, Berkeley, Sulfur Removal Process. An automated gas solubility measurement system was used to collect data on the solubility of hydrogen sulfide, carbon dioxide, propane, and n-butane in a variety of these solvents. The partial pressure of solute gas in these experiments was between 3 and 100 kPa. Correlations for Henry's law coefficients are given as a function of temperature. Gas solubility in the organic solvents decreases when small amounts of water (<6 wt %) are also present. Gas solubility in solvent-water mixtures at the conditions tested is shown to follow a simple mixing rule. An improved correlation is presented for previously published solubility data for sulfur dioxide, which includes the effect of composition as well as temperature on the Henry's law coefficient.
