| titleOfInvention | Energy-saving method and device for a caprolactam system |
| abstract | The invention discloses a method and device for saving energy in a caprolactam system. The device includes a high-pressure benzene distillation tower, a medium-pressure organic solvent rectification tower, a low-pressure organic solvent rectification tower, a low-pressure tower top condenser, a high-pressure tower kettle reboiler, Medium-pressure tower still reboiler, low-pressure tower still reboiler, high-pressure tower top auxiliary condenser and pump, etc.; the organic solvent recovery of the present invention adopts double-effect rectification, and the medium-pressure organic solvent rectification tower top condensation load and low-pressure organic solvent The heat load of the reboiler of the solvent distillation column is matched to realize thermally coupled rectification; the overhead steam of the high-pressure benzene distillation column is used to heat the reboiler of the medium-pressure organic solvent distillation column, which realizes the energy saving of the caprolactam system With optimization, the production cost of caprolactam is greatly reduced. |
