NMP recovery system:

N-Methylpyrrolidone (NMP) is an important chemical raw material, widely used in petroleum processing, fine chemicals, pharmaceuticals, pesticides, electronic products and other fields. It has a pivotal position in the chemical industry and is essential for the manufacture of lithium batteries. Thus after used this materials, there will be waste liquid, in order to protect the environment and ensure not waste the materials, our engineer invent this patent to recycle waste liquid back to use again and did many successful cases.

One good system can save one years’ cost, do you sure you didn’t need one ?

Diagram for NMP recycled system


  1. Recovery performance: The average recovery rate of recovery equipment is as high as 99%, and the average recovery purity is as high as 80%.
  2. Energy-saving performance: Reasonable equipment design, low operating energy consumption.
  3. Operation performance: The equipment can be linked with the coating machine to realize fully automatic operation and fault alarm.
  4. Safety performance: In the exhaust pipe before entering the recovery equipment, a fault handling device is specially installed, even if the alarm is issued, it will not affect the normal production of the enterprise.
  5. Process performance: Reasonable structure layout, beautiful appearance, no leakage in the sealed connection.


N-Methylpyrrolidone (NMP)

N-Methylpyrrolidone (NMP) is a highly polar nonproton transfer solvent with high boiling point, strong polarity, low viscosity, strong solvency, non-corrosive, low toxicity, good chemical and thermal stability, and is completely miscible with water.
and completely miscible with water, etc.
It is mainly used in the fields of coatings, lithium batteries, plastics, chemical production agents, agricultural chemicals, removal, cleaning and degreasing, polymer solvents and polymerization reaction solvents.

Bust the myths behind electric vehicles.

There are three types of production processes for NMP.
One is the pyrrolidone method, which uses pyrrolidone and halogenated alkanes as raw materials.
The second is the synthesis of NMP under catalyst conditions.
The third is the GBL method, which is based on γ-butyrolactone and mixed methylamine or monomethylamine.
At present, the GBL method is mostly based on the mixture of γ-butyrolactone and monomethylamine in aqueous solution.
GBL method is generated by mixing γ-butyrolactone and monomethylamine aqueous solution in a tubular mixer, preheated by a tubular preheater, and reacted in a tubular reactor for 1.5-2.0 hours at a high temperature of 260-290℃ and a pressure of 7.5-8.5Mpa.
