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 (D_c) that is inclined to a general flow direction (D_f) 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).
