Research on NMP Recovery Process from Exhaust Gas of Lithium-ion Battery Coating Machine Oven
With the rapid development of the lithium battery industry,the coating machine,as a key equipment in the production process of lithium batteries,has become increasingly prominent in its exhaust gas treatment problem.Among them,N-methylpyrrolidone(NMP),as one of the main components of the exhaust gas from the coating machine oven,has high recovery value.This study delves into the recovery process of N-methylpyrrolidone(NMP)from the exhaust gas of the lithium-ion battery coating machine oven.By analyzing the composition of the exhaust gas and combining the advantages and disadvantages of existing recovery technologies,an efficient NMP recovery scheme is proposed.This scheme improves the recovery rate of NMP and reduces energy consumption and environmental pollution.The experimental results indicate that the optimized recycling process has significant economic and environmental benefits in industrial applications.
