Multi-channel cross-flow porous device

A multi-channel modular device ( 10 ) processes between two fluid streams of different compositions. The device ( 10 ) includes a porous body ( 150 ) having a first plurality of feed-flow pathways ( 110 ) disposed in the body ( 150 ) for transporting a first stream ( 180 ). A pathway wall ( 114 ) surrounds each of the first plurality of feed-flow pathways ( 110 ) for processing the first stream ( 180 ) into a first composition ( 1852 ) and a second composition ( 1802 ). At least one feed-flow inlet ( 1101 ) is disposed in the body ( 150 ) for introducing the first stream ( 180 ) into the first plurality of feed-flow pathways ( 110 ). At least one feed-flow outlet ( 1102 ) is disposed in the body ( 150 ) for discharging the remaining first stream containing the second composition ( 1802 ). At least one second pathway ( 210 ) is disposed in the body ( 150 ) for transporting a second stream ( 280 ) having a second inlet ( 2101 ) and a second outlet ( 2102 ). A networked plurality of fluid conduits ( 152 ) formed in the porous body ( 150 ) provides the flow-conduit for the second stream ( 280 ) to sweep the first composition ( 1852 ) from each of the first plurality of the feed-flow pathways ( 110 ) to the second outlet ( 2102 ). A vessel ( 300 ) ports the inlets ( 1101 and 2101 ) and outlets ( 1102 and 2102 ) to provide a second stream flow access and for spacing the body within and away from the inner surfaces of the vessel ( 300 ) to provide a gap ( 310 ) for access. A partition ( 350 ) is disposed in the gap between the body and the vessel for diverting the flow within the gap ( 310 ).
