captures, purifies, and often recycles volatile organic solvents, primarily N-Methyl-2-pyrrolidone (NMP), from the drying oven exhaust, using methods like multi-stage condensation, water scrubbing/absorption, and adsorption, ensuring environmental compliance, reducing operating costs by reusing solvent, and improving safety by managing flammable vapors. These systems integrate with the coater, recovering valuable NMP while emitting clean air, crucial for sustainable lithium-ion battery production. 

These systems are vital for large-scale battery manufacturing, ensuring efficiency and environmental responsibility.
