| description | PROBLEM TO BE SOLVED: To provide a separation apparatus for a liquid mixture with excellent separation performance and high energy efficiency while an installation space is compact in a separation operation of the liquid mixture in which it could not be separated only by a specific distillation method. SOLUTION: The separation device for the liquid mixture includes distillation means 3, 4 for separating the liquid mixture of two or more components; and a membrane separation means 13 having a zeolite membrane for separating the vapor mixture distilled from a column top of the distillation means. The device has a pressure control means comprising a pressure regulation valve 6 and two or more condensers 7, 8 arranged in a route for reflux of a part of the vapor mixture to an upper part of the distillation means; and an over-heating adjustment means 12 arranged between the column top of the distillation means 4 and the membrane separation means 13. The distillation vapor from the distillation means 4 is fed to the membrane separation means 13 while making it in the stable over-heating state. The separation performance is made high and reduction of energy consumption of the whole separation device and miniaturization of facility are realized. COPYRIGHT: (C)2007,JPO&INPIT |
