GasTranTM membranes are composite hollow fibers with a thin polymeric layer on the surface of a porous support. The arrangement of shell and fiber bundle for a degassing version is shown in the figure which the two fluid streams separated by the membrane barrier:
1) The shell-side ----------------- Vacuum
2) The internal (lumen) ---------- Liquid feed
