Abstract

A group-contribution model for the correlation and prediction of Henry's constants in single solvents is presented. The mode: involves a one-parameter per gas/ solvent group pair UNIFAC expression extended to incorcorate free volume effects. The model is applied to three gases, CH₄, N₂, and O₂ in alkane solvents and in water. Good results, including a successful description of the temperature dependency of the Henry's constants, are obtained with typical accuracy of ± 10%.
