Title (EN) SIMPLIFIED AUTOMATED DISTILLATION SYSTEM FOR RECOVERING A SOLVENT FROM A LIQUID MIXTURE
(FR) SYSTEME AUTOMATIQUE SIMPLIFIE DE DISTILLATION PERMETTANT DE RECUPERER LE SOLVANT D'UN MELANGE LIQUIDE
Abstract: front page image
(EN)A system is described for recovering a purified distillable component from a starting mixture utilizing a transition tank (20) to receive a transition mixture distilled from a starting mixture, which is returned to the system for further distillation. The system includes a condenser (80) which features an annular tube (82) having cooling fins (85 and 86) arranged inside and outside its annular region to improve its cooling efficiency, and a reflux column (60) which features a flow distributor (65) and a flow centralizer (67) to improve mixing of the rising vapors with the descending liquid. The system also includes a temperature sensor (70) located between the reflux column and the condensor for supplying temperature measurements used in the automatic, operator-less control of the system.
(FR)L'invention porte sur un système permettant de récupérer un composant distillable purifié dans un mélange de départ à l'aide d'une cuve de transition (20) de manière à prélever un mélange de transition distillé à partir du mélange de transition lequel retourne dans le système pour une nouvelle distillation. Le système comporte un condenseur (80) consistant en un tube annulaire (82) muni d'ailettes de refroidissement (85, 86) disposées à l'intérieur et à l'extérieur du tube pour améliorer l'efficacité de refroidissement, un colonne de reflux (60) servant de distributeur de flux (65) et un centralisateur de flux (67) favorisant le mélange des vapeurs ascendantes et du liquide descendant. Le système comporte en outre un thermomètre placé entre la colonne de reflux et le condenseur et fournissant des indications de température pilotant le système automatiquement et sans intervention humaine.
