Claims
- 1. Apparatus comprising a chamber, a tubular integral, three-dimensional structure providing two separate interpenetrating, three-dimensional domains or channels, each of said domains or channels being a closed system of connected porosity or permeability with multiple interconnections only with respect to its respective domain or channel, each of said domains or channels being interpenetrating within said structure, said structure being fluid-tightly fixed at both ends within said chamber such that a closed annular space is provided between the exterior of said tubular structure positioned within said chamber and the interior of said chamber, first fluid inlet and outlet means associated with said chamber for the supply of fluid to one of said channels or flowpaths in said tubular structure and to receive fluid exiting from said one flowpath and second fluid inlet and outlet means associated with said chamber for the supply of fluid to the other one of said channels or flowpaths in said tubular structure and to receive fluid exiting from said other flowpath.
- 2. An apparatus in accordance with claim 1 wherein the material making up said tubular structure and defining the two separate channels or flowpaths therein is made up of a solid, selectively permeable material such that fluid or a component thereof flowing through one of said channels or flowpaths moves into said other channel or flowpath or receives fluid or a component thereof from said other channel or flowpath due to the selective permeability therefor of said material defining said channels or flowpaths.
