DMAC solvent recovery
The low concentration >2% wastewater can be recovered by different treatment processes such as multi effect distillation and heat pump distillation for different concentrations of DMAC wastewater, so that the recovery of low concentration wastewater has considerable economic benefit. The capacity of DMAC wastewater treatment was 5~30t/h, and the recovery rate was more than 99%.
Recovery of water content of DMAC quality less than 200ppm
Containing HAC (acetic acid) less than 30ppm
DMA (two methylamine) less than 20ppm
