Abstract

Il s'agit d'une méthode et d'un appareillage qui permettent d'effectuer la thermotransformation de l'eau contenant des matières cellulosiques en atmosphère inerte. La matière cellulosique est passée en cascade à travers l'appareillage entre de multiples plateaux rotatifs empilés verticalement dans des zones de traitement multiples. La vapeur produite par le chauffage de la matière cellulosique est recyclée par retour à l'appareillage, pour fournir une atmosphère inerte. Cette vapeur peut être surchauffée dans un échangeur de chaleur. Le gaz évacué à partir de la zone de thermotransformation de l'appareillage contient une certaine teneur d'humidité et d'autres éléments volatils qui sont éliminés avant que la vapeur soit chauffée de nouveau dans un brûleur. Le gaz évacué est utilisé dans l'échangeur de chaleur pour surchauffer la vapeur recyclée.
