Abstract

L'invention concerne un procédé et un appareil permettant d'introduire un premier fluide dans un deuxième fluide qui circule dans un conduit. Un premier élément doté d'un canal d'écoulement destiné au deuxième fluide, est au moins partiellement entouré d'une chambre comprenant une paroi entre la partie interne de la chambre et le canal, et une source d'un premier fluide sous pression qui doit être cédé à la chambre. Au moins une série d'ouvertures sont réparties à la périphérie de la paroi en la traversant de telle façon que le premier fluide soit introduit par les ouvertures pour être mélangé au deuxième fluide sur la base de la différence de pression entre la pression régnant dans la chambre et la pression régnant dans le canal d'écoulement. Au moins une partie des ouvertures peut être sélectivement obturée ou fermée pour la régulation du flux du premier fluide entrant dans le canal d'écoulement.
