Title (EN) GAS-LIQUID CONTACTING METHOD AND COLUMN EMPLOYING A COMBINATION OF PLATES AND PACKINGS
(FR) COLONNE ET MÉTHODE DE CONTACT GAZ-LIQUIDE METTANT EN ŒUVRE UNE COMBINAISON DE PLATEAUX ET DE GARNISSAGES
Abstract:
(EN) The gas-liquid contacting column comprises at least an upper plate 10 and a lower plate, and also an overflow 2 for conducting the liquid from the upper plate to the lower plate. The plates have holes through which the gas passes. A packing 11 is placed between the upper plate and the lower plate. The upper plate includes means 12 for withdrawing liquid from the upper plate, the withdrawn liquid being distributed over the packing. The gas-liquid contacting column is particularly well suited for the absorption of CO2 and H2S contained in a natural gas or in a syngas and for the capture of CO2 contained in combustion flue gas.
(FR) La colonne de contact gaz-liquide comporte au moins un plateau supérieur 10 et un plateau inférieur 10, ainsi qu'un déversoir 2 pour conduire le liquide du plateau supérieur au plateau inférieur. Les plateaux comportent des orifices de passage du gaz. Un garnissage 11 est disposé entre le plateau supérieur et le plateau inférieur. Le plateau supérieur comporte des moyens 12 pour soutirer du liquide du plateau supérieur, le liquide soutiré étant distribué sur le garnissage. La colonne de contact gaz-liquide est particulièrement bien adaptée à l'absorption du CO2 et H2S contenu dans un gaz naturel ou dans un gaz de synthèse et au captage du CO2 contenu dans des fumées de combustion.
