Abstract

La demanderesse propose un nouveau procédé d'ozonation d'une phase liquide contenant des particules solides, notamment une pâte à papier. Selon ce procédé, la phase liquide (3), contenant de 0,5 à 5 % en poids de solide, et le gaz (1) contenant l'ozone sont introduits à cocourant dans un réacteur tubulaire (T).
