Abstract

L'invention concerne un corps de milieu séparateur (1) destiné à être utilisé dans un séparateur afin de séparer des goutelettes de liquide d'un flux de gaz ou des goutelettes de liquide d'un premier liquide d'un flux de liquide d'un deuxième liquide, le corps de milieu séparateur (1) présentant une forme de base tubulaire dotée d'un axe médian longitudinal (10) s'étendant sensiblement verticalement dans l'état de fonctionnement et étant constitué d'un milieu pouvant être traversé radialement par le flux de gaz ou de liquide, faisant coalescer les goutelettes de liquide à séparer et les déviant dans la direction de la force de pesanteur. Le corps de milieu séparateur (1) selon l'invention est caractérisé en ce qu'il comprend, vues sur sa longueur axiale (L), au moins deux zones d'épaisseur de milieu radiale (D) différente, l'épaisseur de milieu (D) diminuant, vue dans la direction à partir d'une extrémité supérieure (15) dans l'état de fonctionnement jusqu'à une extrémité inférieure (16) dans l'état de fonctionnement, de 80 % ou moins de l'épaisseur de milieu (D) maximale présente à l'extrémité supérieure (15).
