Abstract
Procédé et appareillage de distillation améliorés. On accroît la température du reflux réintroduit dans une tour de fractionnement, après que ce reflux pénètre dans la tour et avant qu'il parvienne sur le plateau de retour du reflux, en faisant passer le reflux à travers un atomiseur situé dans la tour de fractionnement au-dessus du plateau de retour du reflux et apte à produire une pulvérisation descendante de gouttelettes liquides, en recueillant les gouttelettes sur un plateau à cheminees situé à une distance appropriée entre l'atomiseur et le plateau de retour du reflux, et en faisant passer le liquide collecté du plateau à cheminées sur le plateau de retour du reflux. Application à la mise en oeuvre d'une tour de fractionnement en évitant la désublimation des composés aptes à former des solides.
