DISTILLATION INSTALLATION

摘要

A distillation installation comprises a cross­-corrugated packing module formed from strips of sheet material, comprising corrugations (8) that form alternately first and second main peaks (10; 12) , the corrugations (8) defining channels (14) having a general orientation (Dc) that is inclined to a general flow direction (Df) of a liquid. The strip 2 comprises adjacent rows (R) of inverted portions (22) that lie in the cross section of a channel (14) The strip defines a peak length (LC) between the said rows (R) and an inverted portion length (LPI). The inverted portion length (LPI) 10 different from the peak length (LC). Application to air distillation installations.
