| titleOfInvention | Heterogeneous azeotropic rectification method for separating mixture of 2-pentanone, 4-heptanone, water and carbon dioxide |
| abstract | The invention provides a heterogeneous azeotropic distillation method for separating a mixture of 2-pentanone 4-heptanone, water and carbon dioxide, which is characterized in that 2-pentanone, 4-heptanone to be separated, water and carbon dioxide raw materials enter the left half side of a bulkhead tower from a raw material inlet to be separated of the bulkhead tower to be subjected to gas-liquid separation, a gas phase enters a condenser from a gas phase outlet, a condensate is separated in a gas-liquid separator to obtain a carbon dioxide-rich gas phase, a ketone-rich phase and a water-rich phase, the ketone-rich phase reflows to the left half side of the bulkhead tower, the water-rich phase reflows to the right half side of the bulkhead tower to be extracted to obtain the carbon dioxide-rich gas to be discharged, the ketone-rich phase enters a tower kettle of a rectification tower to obtain a 4-heptanone product, the gas phase discharged from the top of the rectification tower is condensed by a condenser of the rectification tower, one. The invention has the advantages of good separation effect, and capability of greatly saving equipment investment cost and installation space. |
