PLC Control System in DMF Recovery
This is an excellent application for a PLC, as it involves precise control, sequencing, and safety interlocks. Here is a detailed breakdown of a PLC control system for Dimethylformamide (DMF) recovery, typically done through distillation.

MVR in DMF recovery
The MVR (Mother Vapor Recompression) function in DMF (Dimethylformamide) recovery systems is a key energy-saving technology used to enhance efficiency in solvent recovery processes, particularly in industries like pharmaceuticals, chemicals, and synthetic leather manufacturing, where DMF is widely used.

DMAC Solvent Recovery Plant
DMAC Recovery Plant
This DMAC recovery plant uses negative pressure MVR concentration + two-effect vacuum distillation process to separate DMAC from water, and combines with vacuum deacidification tower (refining tower) to obtain DMAC products with excellent index. Combined with evaporation filtration and evaporation of residual liquid, PVP in the waste liquid can be discharged from the system as form of solid residue, which improves the recovery rate and reduces pollution.

DCS Control System
DMF recovery process is a typical chemical distillation process, characterized by a large degree of correlation between process parameters and a high requirement for recovery indicators. From the current situation, the conventional instrument system is difficult to achieve real-time and effective monitoring of the process, so the control is often unstable and the composition exceeds the standard, which affects the production efficiency of enterprises. For this reason, our company and Beijing University of Chemical Technology jointly developed THE DCS control system of DMF recycling engineering computer.

Residue Dryer
The residue dryer pioneered the development and promotion can make the waste residue produced by DMF recovery device completely dry, and form slag formation. To improve the DMF recovery rate, reduce the pollution of the environment, reducing the labor intensity of workers, too. The dryer has been in a number of enterprises to obtain good results.

DMF Waste Gas Recovery Plant
In the light of the dry & wet production lines of the synthetic leather enterprises emitted DMF exhaust gas, the DMF waste gas recovery plant can make the exhaust reaches the requirements of environmental protection, and recycling the DMF components, using high performance fillers make DMF recovery efficiency higher. The DMF recovery can reach above 95%.

DMF Solvent Recovery Plant
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 rectification, and part of the water is recovered and returned to the evaporation tank with DMF for re-evaporation. DMF is extracted from distillation column and processed in deacidification column. The DMF produced from the side line of the deacidification column is cooled and fed into the DMF finished product tank.
