Abstract
A sieve module includes an impermeable housing and an adsorptive media bed. The impermeable housing is puncturable at a first puncture location to receive gas from an exterior of the impermeable housing. The impermeable housing is also puncturable at a second puncture location to expel gas to the exterior of the impermeable housing. The adsorptive media bed is disposed within the impermeable housing. The gas flows through the impermeable housing from the first puncture wound to the second puncture location by flowing through the adsorptive media bed.
