9000 m³/h NMP Solvent Recovery System
This series of NMP recovery systems utilizes the miscibility of NMP and water to recover exhaust gases emitted from coating machines. The system operates fully automatically, ensuring operational stability and safety. It adopts a three-stage spray absorption design, and the tail gas emission is significantly below the national emission standards. The system includes: ventilation ducts, recovery towers, pump groups, blower, NMP liquid storage tank, and control system. The unit features a high recovery rate, low operating cost, compact and aesthetic design, small footprint, excellent performance, and ease of operation—suitable for various lithium battery production lines during the coating process.

1. Process Diagram(Diagram for reference only)
1. Installation Render(Image for reference only)
1. The system recovers NMP from exhaust gases via pure water absorption. Waste gas enters from the bottom, where NMP dissolves in water or steam. After absorption, the gas-liquid mixture passes through a separator and then a rinsing unit to remove remaining NMP. As the waste gas is hot, an energy exchange occurs, causing partial evaporation of water. A circulation pump recycles liquid through the absorption unit, improving heat exchange efficiency and increasing recovered NMP concentration. After processing, exhaust can be discharged directly—essentially achieving zero emissions.
2. Tower Structure
The tower comprises three main zones:
Spray Heat Exchange Section: Enables rapid mass and heat transfer via direct contact between NMP vapors and water.
Mass Transfer Separation Section: Uses structured packing (140Y) for high-efficiency counter-current absorption.
Demisting Section: Captures mist through inertial impaction and swirl separation, with a demisting efficiency of 90–99%.
