A packing structure according to the invention for a fluid contacting column forms a volume comprising an ordered arrangement of bundles of tubes of diameter ranging between 5 and 50 mm. The walls of the tubes comprise orifices which promote circulation and mixes fluids in the structure. The orifices are inscribed in rectangles whose sides range between 2 and 45 mm, and each one of the orifices extends over a surface area greater than 2 mm.

The invention relates to an electrolysis installation comprising at least two rows of electrodes that are immersed at least in part in a liquid electrolyte giving off one or more gaseous species of corrosive nature at the electrodes, at least one separation membrane being disposed between two adjacent rows of electrodes. Each membrane is constituted by carbon fiber reinforcement stiffened by a carbon matrix and presents porous portion that is permeable to ions and impermeable to the or each gaseous species, given off at the electrolytes.
