Industrial DMF Distillation Columns Or Towers

Wuxi Hongdinghua Chemical Equipment Co.,Ltd is one of the professional Industrial DMF Distillation Columns Or Towersmanufacturers and suppliers in China. Industrial DMF Distillation Columns Or Towers is a tower type gas-liquid contact device for DMF distillation. By utilizing the property that each component in the mixture has different volatility, that is, the vapor pressure of each component is different at the same temperature, the light components (low boiling substances) in the liquid phase are transferred to the gas phase, while the heavy components (high boiling substances) in the gas phase are transferred to the liquid phase, thus achieving the purpose of separation. Distillation tower is also a widely used mass and heat transfer device in petrochemical production.

Product Description

Wuxi Hongdinghua Chemical Equipment Co.,Ltd is one of the famous China Industrial DMF Distillation Columns Or Towers manufacturers and suppliers. Our factory specializes in manufacturing of Industrial DMF Distillation Columns Or Towers.  Wuxi Hongdinghua Chemical Equipment Co., Ltd. (HDH) has designed and manufactured many sets of DMF (Dimethylformamide) Distillation Towers based on the parameters and technical conditions provided by customers for many years. The DMF Distillation Tower recovery system designed and manufactured by HDH has not only solved the environmental pollution problem caused by the discharge of wastewater containing DMF,but also brings significant economic benefits to many customers by recycling high-purity DMF.

Working principle of DMF Distillation Tower made by Wuxi Hongdinghua Chemical Equipment Co.,Ltd.(HDH)

HDH fully understands the wide application of DMF in various industrial fields, and also has a comprehensive understanding of the physical and chemical properties of DMF. HDH has accumulated rich experience in designing DMF distillation columns; The working principle of the DMF distillation tower recovery system designed and manufactured by HDH for customers is mainly to utilize the different boiling points of various components (mainly water and DMF) in the DMF recovery effluent liquor, namely volatility (DMF boiling point 153 ℃ and water 100 ℃ under normal pressure). By controlling the temperature of each operation procedure of the DMF distillation tower system, gas-liquid separation is formed, separating water and other impurities one by one from the DMF recovery effluent liquor, thereby achieving the goal of purifying and recovering DMF.

working principle of DMF distillation Tower designned and manufactured by Wuxi Hongdinghua Chemical Equipment

In the actual operation process, Wuxi Hongdinghua Chemical Equipment Co., Ltd.(HDH) prefer to suggest to control that the DMF distillation tower recovery system be under operating condition that the whole distillation condition in a (vacuum)negative pressure state, and the entire distillation system be controlled at a certain temperature. Through continuous heating and condensation, multiple heat exchange processes are completed. According to different boiling points, each component can complete the heat exchange separation process from liquid phase to gas phase, and then from gas phase to liquid phase under a certain temperature controlling, Thus achieving the purpose of purification and recovery of DMF.

Features and Application of DMF Distillation Tower

DMF distillation tower is mainly used for DMF recovery in industries such as polyurethane, acrylic, pharmaceuticals, pesticides, dyes, electronics, etc.

The main components of the DMF distillation tower system are:

Dual tower DMF distillation tower distillation system and recovery system is often used. The DMF distillation tower dual tower system is widely used due to its high recovery efficiency (usually able to recover 8-10 tons of wastewater per hour). The main components of the DMF distillation tower system include:

1. A dehydration tower (slightly lower in height than the DMF distillation tower), which is mainly used to concentrate and recover the DMF effluent liquor,to remove some of the water;

2. The main function of a DMF distillation tower is to achieve more complete separation and purification of DMF through multi-stage distillation;

3. Evaporator, mainly used for heat exchange and preliminary purification of DMF;

4 There are generally two reboilers, which are used for heating the dehydration tower and the DMF distillation tower;

5. Condenser, complete heat exchange, separate and recover DMF and water;

6. The main function of the deacidification and deamination device is to remove impurities such as formic acid and dimethylamine produced by the thermal decomposition of DMF;

7. Vacuum pumps, etc.

Common DMF distillation towers use dual tower systems

General DMF distillation Tower system is dual Tower system--Dehydration Tower & DMF distillation Tower
