DMAC Solvent Recovery Plant-New Technology
DMAC, as an excellent polar solvent, is widely used in polyurethane, pharmaceuticals, pesticides, high molecular membranes (such as PVDF), and electronic chemicals. However, DMAC has certain toxicity and poor biodegradability, and its waste liquid must be effectively treated and recycled.

DMF Effluent Recovery Plant
This proposal is designed for the recovery of DMF effluent generated during process of RO membrane production. Due to the low effluent concentration (~5%), considering the operating cost of the DMF effluent recovery equipment, the process flow is designed based on a three-efficiency energy-saving process, including two-stage concentration and dehydration, one-stage distillation and one-stage deacidification and refining. At the same time, the environmental protection facilities are fully considered to ensure that the entire set of equipment meets the requirements of advanced technology, energy conservation, and environmental protection.

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 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.

DMA Treatment Plant
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.
