DMA Treatment Plant
Main Features
During the DMF rectifying and recovery process, due to the high temperature and Hydrolysis, parts of the DMF will be disintergrated to FA and DMA. The DMA will cause odor pollution, and bring serious impact for the operation environment and the enterprise. To follow the idea of Environment protection, the DMA waste should be incinerated, and discharged without pollution.
We have developed the DMA wastewater purification process, can get about 40% industrial DMA solvent. It makes the DMA become the treasure; can solve the problem of environmental pollution at the same time for enterprises to increase economic benefit.

DMF Solvent Recovery Plant
Process brief introduction After the DMF solvent from the production process is preheated, it enters the dehydrating column. The dehydrating column is provided with heat source by the steam on the top of the rectification column. The DMF in the column tank is concentrated and pumped into the evaporation tank by the discharge pump. After the waste solvent in the evaporation tank is heated by the feed heater, the vapor phase enters the rectification column for rectif...
