The behaviors of different membrane modules for the selective removal and recovery of water vapor and some volatile organic compounds (VOCs) from N2 have been studied. For the selective permeation-based removal of water vapor from N2, a polymeric water-swollen gel membrane in the form of Cuprophan hollow fiber was employed. A thin film composite type rubbery membrane module was studied for the selective removal of VOCs like toluene or methanol from N2 by permeation. The usefulness of pore-condensation phenomenon-based removal of toluene or xylene from N2 was explored using a microporous ceramic tubular membrane.
