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.

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 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.

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 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.

Dry Solvent Recovery Plant
Dry process production line emissions except DMF also contains aromatic, ketones, lipids solvent, pure water absorption on such solvent efficiency is poor, or even no effect. The Company developed the new dry solvent recovery process, revolutionized by the introduction of ionic liquid as the absorbent, can be recycled in the tail gas of solvent composition, and has the great economic benefit and environmental protection benefit.

DMAC Solvent Recovery Plant
This DMAC recovery system uses five-stage vacuum dehydration and one-stage high vacuum rectification to separate DMAC from water, and combines with vacuum deacidification column to obtain DMAC products with excellent indexes. Combined with evaporation filtration and residual liquid evaporation system, the impurities mixed in DMAC waste liquid can form solid residue, improve the recovery rate and reduce pollution.
