NMP Refining System

NRS: NMP Refining System

Our system recycles NMP recovered from the lithium-ion secondary battery manufacturing process into highly pure NMP by using fully automated on-site refining equipment. It is patented in Japan and China.


  • Compatible with all NMP recovery methods (absorption, adsorption, condensation)
  • Refines NMP to a purity of 99.9wt% or higher
  • Extremely low operating cost (UTT, etc.)
  • Comes in a space-saving "skid" type
  • Fully automatic operation

Flexible processing capability design

We will also design and build types not shown in the right diagram to meet your processing capacity requirements.


Our NMP Refining System is useful in lithium ion secondary battery manufacturing facilities.
