Abstract

La présente invention a pour objet un procédé et un dispositif pour la mise en contact de produits sous forme de plusieurs phases et la séparation des produits résultant du mélange. Selon le procédé de l'invention, le mélange est effectué par mise en contact au moyen d'un écoulement puits-tourbillon. Il se caractérise en ce que l'on provoque la séparation des phases par une brusque variation du champ de vitesses d'au moins une phase, tout en maintenant la direction générale des phases. Ce procédé s'applique particulièrement à la concentration de l'acide phosphorique.
