NMP Recovery System

 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
