MEGTEC has developed proprietary systems for high efficiency removal, recovery, and purification of NMP and NEP from coating line exhaust air streams in the lithium-ion battery electrode manufacturing process. These systems can be configured to provide regulatory compliance with global and local emission standards.
MEGTEC Solutions:
To achieve a high rate of recovery with minimum operating costs, MEGTEC utilizes a combination of proven technologies as part of the recovery process. Click to view a simplified flow diagram.
Solvent Recovery
The MEGTEC solution utilizes chilled water condensation of NMP or NEP as the primary means of recovery. A water scrubber provides a secondary means of lowering the NMP or NEP concentration in the exhaust stream to acceptable levels that meet environmental requirements.
Distillation and Purification
Following the recovery of NMP or NEP from the dryer exhaust stream, MEGTEC also provides equipment for the dehydration and purification of NMP or NEP to ultra pure/electronic grade specifications to allow reuse in the manufacturing process. All systems can be supplied pre-assembled on skids for ease of equipment installation.
