Abstract

Separation of SO₂ and NO from a simulated gas mixture using the hollow fiber contained liquid membrane (HFCLM) technique has been explored. Separation of SO₂ from a gas mixture containing SO₂, CO₂, O₂, and N₂ has been studied with pure water and aqueous 1 N NaHSO₃ solution. Combined separation of SO₂ and NO from a simulated flue gas mixture of SO₂, NO, CO₂, O₂, and N₂ has been achieved utilizing aqueous Fe²⁺EDTA or Fe³⁺EDTA solutions. In both cases, sweep and vacuum modes of operation have been investigated. The HFCLM technique has been applied successfully for flue gas cleanup at 24 °C; it was also found to be quite effective at 70 °C. A simplified multicomponent gas permeation model based on solution diffusion through the liquid membrane appears to describe the SO₂ separation as well as CO₂ separation through the water membrane satisfactorily for the sweep mode of permeator operation.
