Abstract:
A packing with cross channel structure for a material exchange column with a high specific separation performance which is specifiable by a specific surface area, a, and an inclination angle of the passages, &phgr;, and which belongs to a class of packings with a=acl and &phgr;=&phgr;cl, comprising:for fluids which flow in the packing, equally large fluid flows are in each case provided; a number n of theoretical separation stages per meter which can be empirically determined for the packing, wherein the parameter NTSM can be represented by a first function f1(a, &phgr;) of the variables a and &phgr;; a flow resistance which results for a gas flow which flows through the packing can be characterized by a pressure loss per meter, &Dgr;p, as a second function f2(a, &phgr;); and under an auxiliary condition n=const, &Dgr;p assumes a relative minimum for which the variables a and &phgr;â€”in dependence on the parameter nâ€”assume the values am(n) and &phgr;m(n) respectively; wherein n>4.5, aclm(n), &phgr;cl>&phgr;m(n) and &phgr;cl>45Â°.
