Abstract
The invention relates to a packing structure (1) for a fluid exchange column, the packing structure defining an exchange surface for at least one down-flowing liquid phase that is to be put into intimate contact with at least one up-flowing gas phase, the structure including a volume formed by a plurality of rows of bundles of tubes (10), each bundle having four tubes (10a-10d) respectively oriented along four directions (D10a-D10d) forming an angle relative to the axis of the structure, the plurality of tubes forming a plurality of passages opening out to the outside surface of the structure (1).
Claims16
A packing structure for a fluid exchange column, said structure defining an exchange surface for at least one down-flowing liquid phase that is to be put into intimate contact with at least one up-flowing gas phase, the structure being characterized in that it comprises a volume formed by a plurality of rows of bundles of tubes, each bundle comprising four tubes respectively oriented along four directions forming an angle relative to an axis of the structure, the plurality of tubes forming a plurality of passages opening out to an outside surface of the structure, each of the tubes made of carbon-carbon or ceramic composite material and each of the tubes presenting macropores providing passages between insides and the outsides of the tubes.
