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
