Abstract
An apparatus is disclosed for dehydrating gas in a system having control gas and supply gas. A first housing is fluidly connected to supply gas and a first membrane member is in the first housing flow path, with a plurality of tubes having interstitial spaces therebetween, each tube being more permeable to water vapor than to gas. Supply gas exiting the first membrane member is drier. Drier supply gas is metered to the first membrane member interstitial spaces, whereby dried supply gas sweeps water or water vapor from the first membrane member interstitial spaces to surrounding environment. A second housing similar to the first has a similar second membrane member therein and fluidly connected to control gas. Control gas exiting second membrane member is drier. Drier supply gas is also metered to second membrane member interstitial spaces, and sweeps water or water vapor from second member interstitial spaces through the second housing vent.
