An air separation module includes a canister, a separator, and a perforated plate. The canister has a plenum portion connecting an inlet portion to an outlet portion, extends circumferentially about a canister axis, and has a plenum diameter that is larger than a canister diameter defined by the inlet and outlet portion of the canister. The separator is arranged within the canister and axially spans the plenum portion to separate air received at the inlet end portion into nitrogen-enriched and oxygen-enriched air flows. The perforated plate is seated within the plenum portion, fluidly couples the separator to an oxygen-enriched air outlet port defined by the plenum portion, and has a snap-fit major dimension smaller than the plenum diameter to radially support a portion of the separator axially spanning the plenum portion of the canister. Nitrogen generation systems and methods of making air separation modules are also described.

Membrane filter apparatus with internally supported filter assembly

A membrane filter apparatus for splitting a feed into filtrate and retentate is provided. The apparatus comprises a body chamber, a feed inlet disposed on the body chamber, a retentate outlet located in the body chamber, a feed distribution tube connected to the feed inlet, and a filter assembly having a filter. The feed distribution tube has a length sufficient to cause the feed to enter the body chamber at a feed distance from the filter assembly of no greater than 50% of a total length of the body chamber. The feed flows across the filter in a direction parallel to a surface of the filter assembly. The filtrate passes through the filter assembly and the retentate flows through the body chamber in a direction antiparallel to the feed flow through the feed distribution tube and out through the retentate outlet.

MODULAR, DISPOSABLE 3D PRINTED MICROFLUIDIC MEMBRANE SYSTEM FOR SEPARATION AND PURIFICATION

The present disclosure relates to a membrane extraction apparatus for extracting a component from a first liquid.
