Abstract
A deaeration assembly for removal of air or other gases dissolved in a liquid. The assembly includes a deaeration element having a gas-channel-forming component enclosed and sealed within an envelope which includes a nonporous fluoropolymer film. The assembly also includes a liquid-channel-forming component which can be positioned on the outside of the element, or can be enclosed with the gas-channel-forming component within the element. The assembly can be formed in spiral-wound or folded configurations for installation in a deaeration module or apparatus. The deaeration assembly is useful for removal of gases dissolved in chemically aggressive liquids, high-purity liquids, and other special liquids.
