ZJRH NMP Recovery System

NMP content in discharge air is ≤12ppm
NMP Recovery rate can reach 99%

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 :

1. Relative humidity of purified air to be circulated to coating machine is ≤2%RH

2. 90% of purified air is circulated in the system to reduce power consumption

3. NMP content in discharge air is ≤12ppm

4. NMP Recovery rate can reach 99%

5. Concentration of recovered NMP Solvent ≥85%

6. Heat exchage rate is ≥75% and temperature of the air to be circulated after the heat ex-changer can reach 90℃

Functional section：Heat Ex-changer,Cooler, VOC concentrator,process fan, Solvent Storage tank(optional)；Siemens PLC
