The separation of sulfur dioxide and nitrogen by permeation through a sulfolane plasticized vinylidene fluoride film was investigated. The membrane is effective for the separation of SO/sub 2/ from a binary mixture with nitrogen. Depending on permeator conditions, actual separation factors varying from about 30 to 100 and fluxes varying from 0.02 to 1.86 scfd/sq ft are observed for the optimum membrane composition containing about 8.2 wt percent sulfolane. Feed gas pressures of 100 to 500 psig were investigated. The membrane selectivity is highly dependent on feed and membrane composition, and on permeator pressure.
