SIMPLIFIED AUTOMATED DISTILLATION SYSTEM FOR RECOVERING A SOLVENT FROM A LIQUID MIXTURE

摘要

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.
