Method for producing a non-porous membrane

摘要

A non-porous membrane (64) suitable for use in removing dissolved oxygen in a fuel deoxygenator device in an aircraft is produced by solvent casting. A first membrane layer (66) is deposited on a substrate (78). A second membrane layer (68) is deposited on top of the first membrane layer (66). Subsequent membrane layers may be deposited on top of the second membrane layer (68) as desired. The resulting non-porous membrane (64) allows little or no leaking of fuel across the membrane.
