This system is designed to recycle NMP from the lithium-ion secondary battery electrodes manufacturing process. The hot solvent laden air from the ovens is drawn into DRYAIR’s NMP Recovery System where the NMP is recovered by a combination of condensation and adsorption.The cleaned solvent laden air is available for return to the process or discharge to atmosphere as per customer requirement.NMP stands for N-Methyl-2-Pyrrolidone,it is an expensive solvent In addition, the recovery and recycling of NMP can reduce running costs for lithium battery factories as well as avoiding air pollution.
Features :
97% recovery rate
NMP discharge: 12ppm
Conentration of recovered NMP Solvent:85%
Functional section：
Heat Ex-changer,Cooler
VOC concentrator,Process fan
Solvent Storage tank(optional)
Siemens PLC
