The company's own research and development of ONPS® process (On-site NMP Purification System) can be used for lithium industry NMP solvent recovery and purification. The whole system has no tower equipment, integrates the waste liquid treatment system to realize zero discharge, the whole system runs automatically, can choose the cycle operation and the continuous treatment mode, the NMP purity of the product is more than 99.9%, the water content is less than 50ppm, and the recovery rate is more than 99%.
| ● Small area, high integration, can be fully driven by electricity; | ● High efficiency dehydration, one way to reach 5~200ppm index; |
| ● Zero emissions, no worries about environmental protection; | ● Quick start and stop, full automatic operation; |
