This system recovers NMP from exhaust gas generated during the lithium-ion battery electrode manufacturing process. It minimizes solvent emissions into the atmosphere and recovers the expensive solvent at high concentrations, thereby reducing the cost of refining the recovered solvent.

This groundbreaking system recovers NMP used in lithium-ion battery manufacturing processes, achieving significant energy savings and high environmental performance.
With NMP recovery efficiency of 99% and waste heat recovery efficiency exceeding 60%, it enables 100% recycling of exhaust gas back into the production equipment.
Since delivering the first unit in 1995, we have a proven track record of delivering a total of 45 units by 2020.
