Abstract

L'invention porte sur une structure à plateaux d'une tour de traitement chimique, cette structure comprenant un trop-plein semi-conique (120) adapté pour l'évacuation du liquide le long d'une partie marginale courbe d'un plateau sous-jacent (130). Ce plateau sous-jacent (130) est soutenu dans la tour de traitement chimique au moyen d'un élément annulaire de support (98) placé sous le bord du plateau. Cet élément annulaire de support solide (98) forme généralement une surface non active sous cette région du plateau, et le trop-plein semi-conique déverse le liquide directement sur la région inactive, la partie libre du plateau pouvant être utilisée pour un transfert de matière.
