The Company engaged in the design and installation work of the DMF solvent recovery equipment for many years. "Technology leadership and customer first" are its principle. It has developed single tower -single effect to seven towers - four effect of DMF solvent recovery device. DMF wastewater treatment capacity is 3~ 50t / h. Recovery device comprises an evaporating concentration, distillation, de-amination, residue processing, tail gas treatment process. Technology has reached the international advanced level, and for the Republic of Korea, Italy and other countries of the export of complete sets of equipment.
The quality of the DMF recovery solvent up to the synthetic level:
Water ≤200ppm
FA ≤25ppm
DMA ≤15ppm
Electrical conductivity ≤2.5µs/cm
Rate of recovery ≥99%
