A fluid inlet device (1) suitable for introducing a mixture of liquid and gas into a vessel, which fluid inlet device comprises a guide member having a surface on which surface a liquid film is present during normal operation, and having a main direction of gas flow along the surface; and wherein the guide member (20) is provided with a liquid catcher channel (40) extending from an upstream position with respect to the guide member (20) to a downstream position, and wherein a virtual line along the guide member between the upstream position and the downstream position deviates from the main direction of gas flow; the use of the fluid inlet device for introducing a mixture of liquid and gas into a gas-liquid contacting vessel; and a method of retrofitting a fluid inlet device.
L~invention concerne un dispositif (1) d~admission de fluide apte à introduire un mélange de liquide et de gaz dans un réservoir, le dispositif d~admission de fluide comprenant un élément de guidage présentant une surface revêtue d~une pellicule liquide en mode de fonctionnement normal et offrant une direction principale d~écoulement de gaz. Le dispositif d~admission de fluide est caractérisé en ce que l~élément de guidage (20) est doté d~un passage (40) de collecte de liquide s~étendant d~une position amont par rapport à l~élément de guidage (20) à une position aval, et en ce qu~une ligne virtuelle le long de l~élément de guidage reliant la position amont et la position aval s~écarte de la direction principale d~écoulement de gaz. L~invention concerne également l~utilisation du dispositif d~admission de fluide pour introduire un mélange de liquide et de gaz dans un réservoir de mise en contact gaz-liquide, ainsi qu~un procédé de montage à postériori du dispositif d~admission de fluide.
