N2 & O2 Membrane Units

Membrane Units for Air Separation Applications:

> N2 Purification (95% to 99.9%)

> O2 Enrichment

> O2 Removal

> Dehydration H2O Removal for Air Drying


Gulf Gases will work with you to understand your unique application requirements, then design, build & deliver the right membrane configuration in a system that�s correctly optimized for meeting your Air, Nitrogen, Oxygen & Drying applications, plus removal of any related trace compounds & impurities. 


Gulf Gases will select the right polymeric membrane and module for your application.  We build on the experience of thousands of installed units in hundreds of different application environments. 


Polymeric Membranes are unique gas separation polymers with engineered characteristics of permeability, selectivity and diffusion resistance.  The Polymeric Membranes used in these units have been designed to best fit Air, N2 and O2 related process needs.  After pre-treatment to remove coalescents and particluates, the separation of gas components in the feed air is performed by the individual permeation rate of each component through the membrane wall structure.  Production is continuous at constant flow, pressure and purity.
