ABSTRACT:
A material is provided for use as a tower packing and/or as the separation medium in mist eliminators. Also provided are methods for producing the new material. The new material is comprised of woven strands, or at least two sets of strands interleaved together in directions perpendicular to each other, with the strands in either the warp or filling direction being essentially straight, while those in the other direction are geometrically reoriented or otherwise configured through the straight strands in a specific manner and, preferably, joined together at intersecting points, to produce a material having substantial thickness in cross section. All of the individual strands of the material, when placed for use, will be essentially perpendicular to the fluid flow being treated. As a result, the material of the invention provides a substantial increase in the void fraction for mist elimination and a substantial increase in impact contact surfaces for tower packing applications.
