Abstract:
A corrugated strip for use as a cross-corrugated packing in a distillation column, the corrugated strip comprising on its lower edge, seen face on, at least one downwardly projecting motif whose contour is such that, if .alpha..sub.m and .alpha..sub.M designate the extremes of the algebraic value of the angle that the tangent of the contour, oriented in one direction of said lower edge forms with a horizontal line oriented in said one direction, then-.alpha..sub.m >.alpha..sub.0 and .alpha..sub.M >.alpha..sub.0,wherein .alpha..sub.0 designates a predetermined angle equal at least to 5.degree.; andwherein each motif is obtained by bending a flat strip to form a corrugation of height H, opening angle .gamma. and radius r at the peak of the corrugation, with the generatrices of the corrugations inclined at an angle .delta. seen face on, the parameters H, .gamma., r and .delta. being selected such that ##EQU3##
