Patent EP-0084554-A1 (EP)
Inventor: HUSSMANN PETER
IPC: B01D29/00
Filed: 1982-08-02
Abstract: Selon le procédé d'extraction de substances, en particulier à partir des matières riches en arômes, on mélange successivement par étapes, à chaque cycle, plusieurs quantités de solvants d'extraction de différentes concentrations avec la substance d'extraction moulue très finement, substance qui est renouvelée après chaque cycle. Le procédé commence avec le solvant ayant la plus haute concentration (I) et se termine avec le solvant ayant la plus petite concentration (XIII). Après la formation de chaque mélange (2), on sépare à nouveau (3) du mélange un solvant enrichi d'extraits, le solvant ayant la plus haute concentration (0) étant évacué et remplacé par du solvant frais et les autres solvants séparés sont stockés pour le cycle suivant. Avec chaque cycle on mélange (5, 6) au moins une fois et de manière intensive la substance d'extraction avec une quantité de solvant, ce mélange étant obtenu dans un agitateur intensif ou dans un broyeur à boules, en obtenant ainsi une augmentation du rendement. La température du procédé correspond à la température ambiante et le dispositif de mise en oeuvre du procédé présente un extracteur ayant un lit filtrant plat (2), dans lequel est prévu un dispositif de nettoyage de la matière filtrante (3). Le dispositif de nettoyage présente, au-dessous de la matière filtrante, une buse rotative de laquelle est expulsé, sous une haute pression, un produit de purification qui traverse la matière filtrante de bas en haut. Par le nettoyage de la matière filtrante on obtient une accélération de la séparation dans l'extracteur.

Abstract: Procédé de préparation d'urée à partir d'ammoniac et d'anhydride carbonique à une température et à une pression élevées ayant une zone de réaction et une zone d'extraction. Dans la zone de réaction, l'anhydride carbonique et une partie de l'ammoniac sont convertis en carbamate d'ammonium, et une partie du carbamate d'ammonium est convertie en urée, les conversions combinées donnant un fort dégagement de chaleur. Dans la zone d'extraction, un courant de produit d'urée contenant du carbamate d'ammonium non converti est chauffé par échange de chaleur avec la zone de réaction pour décomposer une partie du carbamate d'ammonium. Dans la zone de réaction, la conversion du carbamate d'ammonium en urée est continuée jusqu'à ce que la quantité d'urée formée soit au moins égale à 50 % de la quantité d'urée qui serait obtenue dans des conditions de réaction d'équilibre régnant dans la zone de réaction.
