| description | The utility model relates to an acetic anhydride rectification energy-saving process device, which adopts differential pressure rectification and comprises a low-boiling-point removal tower feeding steam heater, a low-boiling-point removal tower, a low-boiling-point tower condenser, a low-boiling-point tower kettle steam heater, a raw material heater, a finished product tower and a finished product tower kettle steam heater, the low-boiling-point removal tower is communicated with the finished product tower, and the raw material heater is respectively connected with the low-boiling-point removal tower feeding steam heater and the finished product tower. Before implementation, the process devices are all independent rectifying towers, differential pressure coupling is not carried out, the energy-saving effect of the implemented process devices is remarkable, the original process is slightly changed, and the product yield and quality are not influenced.
