The invention concerns a dispenser (1) comprising: a primary dispenser (3) defining a closed volume provided with openings (8) for pre-dispensing liquid emerging in the column; means for supplying the primary dispenser (3) with liquid under pressure very much higher than the pressure inside the column; and a secondary dispenser (4) taking up substantially the whole section of the column, which comprises a gaseous roof communicating with the column internal space and which is subdivided by internal partitions (13, 17) into a plurality of compartments (16) each of which receives the liquid coming from at least one of the primary dispenser (3) said orifices (8), said secondary dispenser (4) comprising a base (9) provided with orifices (12) dispensing fine liquid over almost the whole section of the column, said orifices being much more numerous than the primary dispenser openings (8). The invention is applicable to air distilling on offshore floating terminals or on drilling platforms.
Ce distributeur (1) comprend: un distributeur primaire (3), qui délimite un volume clos muni d'ouvertures (8) de prédistribution de liquide qui débouchent dans la colonne; des moyens d'alimentation du distributeur primaire (3) en liquide sous une pression nettement supérieure à la pression intérieure de la colonne; et un distributeur secondaire (4) qui occupe sensiblement tout la section de la colonne, qui comporte un ciel gazeux en communication avec l'espace intérieur de la colonne et qui est subdivisé par des cloisons (13, 17) en une pluralité de compartiments (16) dont chacun reçoit du liquide en provenance d'au moins l'une desdites ouvertures (8) du distributeur primaire (3), ce distributeur secondaire (4) comportant un fond (9) muni d'orifices (12) de distribution fine du liquide sur pratiquement toute la section de la colonne, ces orifices étant en nombre très supérieur au nombre d'ouvertures (8) du distributeur primaire. Application à la distillation d'air sur des plates-formes pétrolières flottantes ou sur des barages.
