GasTran^TM

A New Class of High-Selectivity Membranes for Bubble-Free Gas Transfer to or from Aqueous Solutions

GasTran^TM membranes are composite hollow fibers with a thin polymeric layer on the surface of a porous support. When gas is transfered, the membrane functions mainly as a barrier between gas-gas and gas-liquid phases. To perform well, it must have a high mass transfer rate for gases, be essentially impermeable to water, and have good mechanical strength. NeoMecs applies such a layer by the precisely controlled process of plasma polymerization.

Practical use of the GasTran hollow-fiber membrane has led to the module design shown below. It has a compact and convenient structure which provides many options of total membrane surface area through choice of fiber bundle size. The external shell has versatile connections to bring into the module the two fluid streams separated by a membrane barrier.
