Abstract
Abstract The random or statistical packing is of hexagonal cross-section and has rectangular tongues and apertures punched out of the walls. The tongues extend towards the longitudinal axis of the packing with the opposite tongues being coplanar. The planes of the tongues are substantially parallel to the sides of the packing so that crossing channels arise for the passage of a gas. The packing has substantially the effect of a regular packing such that a satisfactory lateral distribution of liquid and gas with a relatively low pressure drop is obtained.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
61 words
A statistical packing having a peripheral wall defining a polygonal shape, a plurality of tongues extending inwardly of said wall to define gaps in said wall, a plurality of apertures in said wall disposed circumferentially of said tongues and gaps, and solid surface portions disposed circumferentially of said tongues and apertures, said packing having a length greater than the diameter thereof.
Claim 2
Dependent Claim
61 words
A statistical packing having a peripheral wall defining a polygonal shape, a plurality of tongues extending inwardly of said wall to define gaps in said wall, a plurality of apertures in said wall disposed circumferentially of said tongues and gaps, and solid surface portions disposed circumferentially of said tongues and apertures, said packing having a length greater than the diameter thereof.
Claim 3
Dependent Claim
30 words
A statistical packing as set forth in claim 1 wherein said tongues are disposed in staggered relation to each other longitudinally of said wall with diametrically disposed tongues being co-planar.
Claim 4
Dependent Claim
40 words
A statistical packing as set forth in claim 1 wherein said wall has a plurality of sides, each side having a tongue, an aperture and a solid surface portion aligned in the direction of the longitudinal axis of the packing.
Claim 5
Dependent Claim
21 words
A statistical packing as set forth in claim 3 wherein said tongues of adjacent walls are staggered relative to each other.
Claim 6
Dependent Claim
23 words
A statistical packing as set forth in claim 1 having a length of from 1.5 to 2 times greater than a diameter thereof.
Claim 7
Dependent Claim
39 words
A statistical packing as set forth in claim 1 wherein each said tongue extends parallel to and toward a longitudinal axis of said packing to form a channel for a flow of gas between a pair of adjacent tongues.
Claim 8
Dependent Claim
23 words
A statistical packing as set forth in claim 1 wherein adjacent tongues are circumferentially offset from each other at an angle of 60°.
Claim 9
Dependent Claim
20 words
A statistical packing as set forth in claim 1 wherein said surface portions and said tongues are provided with apertures.
Claim 10
Dependent Claim
