Patent ID: 8827248

Claim:
An assembly comprising a first pathway for a first fluid, the first fluid being a gas, a second pathway for a second fluid, the second fluid being a liquid, wherein the first and second pathways cross each other at a fluid crossing region, the assembly including a matrix arrangement disposed at said fluid crossing region, the matrix arrangement allowing the first and second fluids to contact one another, the matrix arrangement comprising a plurality of generally planar sheets generally aligned with the second pathway, each sheet defining a plurality of apertures for the flow of the first fluid such that the first fluid crosses the second fluid in a direction transverse to the flow of the second fluid along a segment of the first pathway between a first aperture in a first sheet and a second aperture in a second sheet generally parallel to the first sheet, and wherein the first fluid must pass through the apertures in order to flow along the first pathway and the second fluid may flow along the second pathway without passing through the apertures.
