Preparation of Gas Separation Membranes and their Evaluation
Keywords: Asymmetric membrane, phase-inversion technique, permeability, membrane selectivity, Polysylfone
AbstractAsymmetric membranes have been prepared form the polysulfone using dry-wet phase-inversion technique. These membranes show a thin dense skin at one surface and porous as well as the selectivity of membranes. In addition an online permeate composition analysis system has also been setup to quantify the concentration fo the two major components of atmospheric ari, namely oxygen and nitrogen using a gas chromatograph. Memvranes have been tested at various feed pressures. Teh developed membranes are capable of enriching atmospheric air to a level of 30 per cent and more.
