| titleOfInvention | Refining system containing cyclopentanone and propylene glycol methyl ether acetate recovered liquid |
| abstract | The utility model discloses the refining systems containing cyclopentanone and propylene glycol methyl ether acetate recovered liquid, including pretreatment kettle, first rectifying column, Second distillation column, third distillation column and the 4th rectifying column；The discharge port of pretreatment kettle is connected to first rectifying column, and the tower bottom liquid-phase outlet of first rectifying column is connected to the feed inlet of Second distillation column；The top gas phase discharge port of Second distillation column is communicated with the feed inlet of third distillation column, and the tower bottom discharge port of third distillation column is connected to cyclopentanone splice jug；The tower bottom liquid-phase outlet of Second distillation column is communicated with the feed inlet of the 4th rectifying column, and the tower top discharge port of the 4th rectifying column is connected to by condenser with propylene glycol methyl ether acetate splice jug.Based on the method that refining system uses continuous rectification, low energy consumption, and production process is safe and reliable, and the yield of resin raffinate is few, and for the product purity by film filtering up to 99.91% or more, product coloration and other indexs can reach electronics grade standard, realizes product reuse. |
