NMP Recovery System

The NMP (N-Methyl-2-Pyrrolidone) recovery equipment is a highly efficient and energy-saving solvent recovery system, specifically designed for the recovery of NMP exhaust gas generated in the lithium battery cathode coating process. Utilizing condensation, adsorption, it achieves an NMP recovery rate of ≥99%, significantly reducing production costs and meeting environmental requirements. The system integrates a heat recovery system, reducing energy consumption by over 30%, and is equipped with a PLC automatic control system and modular design, enabling fully automated operation and flexible expansion. Compliant with ATEX explosion-proof standards, it ensures safe and reliable operation. Widely used in lithium battery manufacturing, chemical, electronics, and pharmaceutical industries, the NMP recovery equipment, with its high efficiency, energy-saving, and eco-friendly features, provides customers with sustainable solutions, helping to reduce costs, improve efficiency, and achieve green production.

     Application field：
       Suitable for the coating process in the manufacturing of lithium battery cell pilot lines;
       Suitable for the coating process in the manufacturing line of lithium battery cells;
       The air pollution control equipment in the NMP recovery system is suitable for laboratory scale coating equipment.

    Equipment advantage：
       Heat exchange between the high temperature exhaust air and the low temperature return air: saving energy costs;
       No cooling water is required due to more efficient condensing host;
       90-95% return air design;
       G4 filter for particle control;
       Waste heat recovery unit and condensing host can be integrated;
       5-10% Tail gas treatment with VOC adsorption rotor (single or double) to meet the emission standard (10-50 mg/Nm3, with laboratory measured data low to 1 mg/Nm3);
       Emergency emission strategy: activated carbon filter when rotor fails. (optional)

    Process flow：
       Cathode processing technology: waste heat recovery + condensation with 95% return air + 5% emission with water absorption tower treatment
       Cathode processing technology: waste heat recovery + condensation with 95% return air + 5% emission with adsorption rotor treatment
       Anode processing technology: waste heat recovery + condensation with 95% return air + 5% emission 
       Anode processing technology: waste heat recovery + condensation + 100% emission
