Abstract
Abstract The packing is constructed for an exchange column and is provided with corrugated lamellae which have steep portions disposed between the various corrugations in order to accelerate the descending liquid phase between the corrugations. The steep portions are vertically arranged between adjacent corrugations or between pairs of adjacent corrugations.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
87 words
A packing for an exchange column comprising a plurality of corrugated lamellae disposed in vertical parallel relation, each said lamella having a plurality of corrugations disposed in angular crossing relation to the corrugations of an adjacent lamella to form a plurality of flow channels and at least some of said lamellae having at least one steep portion interrupting two adjacent flow channels with said corrugations thereof disposed in an alternating pattern relative to opposite sides of said respective lamella and relative to a plurality of steep portions.
Claim 2
Dependent Claim
87 words
A packing for an exchange column comprising a plurality of corrugated lamellae disposed in vertical parallel relation, each said lamella having a plurality of corrugations disposed in angular crossing relation to the corrugations of an adjacent lamella to form a plurality of flow channels and at least some of said lamellae having at least one steep portion interrupting two adjacent flow channels with said corrugations thereof disposed in an alternating pattern relative to opposite sides of said respective lamella and relative to a plurality of steep portions.
Claim 3
Dependent Claim
18 words
A packing as set forth in claim 1 wherein each said steep portion extends at least substantially vertically.
Claim 4
Dependent Claim
80 words
A packing for an exchange column comprising a plurality of corrugated lamellae disposed in vertical parallel relation, each said lamella having a plurality of corrugations disposed in angular crossing relation to the corrugations of an adjacent lamella to form a plurality of flow channels and at least some of said lamellae having at least one steep portion interrupting two adjacent flow channels with said corrugations thereof defining a pair of flow channels on each side of a respective steep portion.
Claim 5
Dependent Claim
80 words
A packing for an exchange column comprising a plurality of corrugated lamellae disposed in vertical parallel relation, each said lamella having a plurality of corrugations disposed in angular crossing relation to the corrugations of an adjacent lamella to form a plurality of flow channels and at least some of said lamellae having at least one steep portion interrupting two adjacent flow channels with said corrugations thereof defining a pair of flow channels on each side of a respective steep portion.
Claim 6
Dependent Claim
77 words
A packing for an exchange column comprising a plurality of corrugated lamellae disposed in vertical parallel relation, each said lamella having a plurality of corrugations disposed in angular crossing relation to the corrugations of an adjacent lamella to form a plurality of flow channels and at least some of said lamellae having at least one steep portion interrupting two adjacent flow channels with said corrugations thereof disposed in pairs to each side of a respective steep portion.
Claim 7
Dependent Claim
77 words
A packing for an exchange column comprising a plurality of corrugated lamellae disposed in vertical parallel relation, each said lamella having a plurality of corrugations disposed in angular crossing relation to the corrugations of an adjacent lamella to form a plurality of flow channels and at least some of said lamellae having at least one steep portion interrupting two adjacent flow channels with said corrugations thereof disposed in pairs to each side of a respective steep portion.
Claim 8
Dependent Claim
27 words
A packing as set forth in claim 4 wherein said paris of corrugations of a respective lamella are disposed on only one side of said respective lamella.
