Abstract
The packing for a counterflow high pressure column contains an ordered array of shaped lamella aligned parallel to the column axis. The packing comprises a bundle of strings extending in the direction of the column axis. Each string consists of a stack of packing elements, with adjacent elements belonging to different strings respectively forming a packing section perpendicular to the column axis. Each packing element is constructed in layers formed by the lamella. The layers are oriented in such a manner that gap-like or channel-like intermediate spaces between the lamella are laterally bounded by transversely lying lamella of adjacent packing elements belonging to the same packing section.

A packing for a counterflow high pressure column which has a column axis, the packing comprising:
- a bundle of strings extending in a direction of the column axis, each of the strings including a stack of packing elements which each comprise a plurality of layers of shaped lamella, each group of adjacent packing elements from different strings of the bundle forming a packing section generally perpendicular to the column axis, the layers of shaped lamella of each packing element oriented with intermediate spaces between the shaped lamella being bounded by transversely disposed lamella of adjacent packing elements in each packing section, the stack of packing elements in each of the strings being eccentrically arranged relative to the string center line with the side surfaces of adjacent packing elements in the string being offset slightly with respect to one another.
A high pressure column for material and heat exchange or for chemical reactions which occur between a trickle film and a gaseous or vapor-like phase moving in counterflow, the column containing a packing which has a column axis, the packing comprising a bundle of strings extending in a direction of the column axis, each of the strings including a stack of packing elements which each comprise a plurality of layers of shaped lamella, each group of adjacent packing elements from different strings of the bundle forming a packing section generally perpendicular to the column axis, the layers of shaped lamella of each packing element oriented with intermediate spaces between the shaped lamella being bounded by transversely disposed lamella of adjacent packing elements in each packing section, the stack of packing elements in each of the strings being eccentrically arranged relative to the string center line with the side surfaces of adjacent packing elements in the string being offset slightly with respect to one another, wherein a liquid distributor is placed above the packing to form a largely uniform liquid distribution over the packing.
A packing for a counterflow high pressure column which has a column axis, the packing comprising:
- a bundle of strings extending in a direction of the column axis, each of the strings including a stack of packing elements which each comprise a plurality of layers of shaped lamella, each group of adjacent packing elements from different strings of the bundle forming a packing section generally perpendicular to the column axis, the layers of shaped lamella of each packing element oriented with intermediate spaces between the shaped lamella being bounded by transversely disposed lamella of adjacent packing elements in each packing section, the stack of packing elements in each of the strings being eccentrically arranged relative to the string center line with the side surfaces of adjacent packing elements in the string being helically offset with respect to one another, the layers of adjacent packing elements that are eccentrically arranged in each of the strings being arranged to lie transverse to each other.
