Abstract:
1. An apparatus comprising: a hollow fiber contactor having a plurality of hollow fiber membranes contained within a housing; said hollow fibers having a lumen side and shell side separated by a porous membrane, said lumen side of said fibers in fluid communication with a first inlet and a first outlet of said housing, and said shell side in fluid communication with a second inlet and a second outlet of said housing; said first or second inlet in-line with a source of gas comprising an impurity from an outlet of an etch tool, an outlet of a deposition tool, or a feed from a recirculated glove box or a photoresist cleanrooms, said hollow fiber contactor connected to a reactive fluid from a reactive fluid reservoir to direct the reactive fluid at the opposite hollow fiber membrane side, to form a gas with a reduce impurity content; one of said first outlet or said second outlet from said hollow fiber contactor for removing said gas with reduced impurity content and one of the first or second outlets for removing the reactive fluid; and a sensor to monitor the composition of gas with reduced impurity content removed from said hollow fiber contactor.
