Efficient Solvent Recycling with Activated Carbon
Solvent recovery is to recycle organic waste gas through a certain recovery process and reuse it in production to reduce air pollution and production costs. Activated carbon plays an important role in solvent recovery. This article will explore the application of activated carbon in solvent recovery, introduce its principles and advantages, and help you understand how to achieve efficient and environmentally friendly solvent reuse through activated carbon.
How does activated carbon work for solvent recovery?
In the process of solvent recovery, activated carbon is a widely used key technology. When the organic solvent vapor passes through a specially designed activated carbon adsorption tower, the unique porous structure and high surface area of activated carbon are used to effectively adsorb and remove the organic components in the solvent.
The excellent adsorption performance of activated carbon enables it to maintain efficient working state for a long time. When the activated carbon is saturated with adsorption, it can be recycled by steam regeneration. During the steam regeneration process, high-temperature steam passes through the activated carbon bed, releasing the organic matter adsorbed in it, thereby reactivating the adsorption capacity of the activated carbon. This renewability allows the activated carbon to be recycled, greatly improving its economic and environmental sustainability.
Customer case
For tape and PVC film factory, it will occur toluene, ethyl, and acetate. Solvent recovery for these gases is highly economical.
We have served activated carbon to the biggest tape factory in China for many years. Every time, we will provide 210tons of activated carbon for solvent recovery.
There are 30 tanks in this tape factory. Every tank will load 7ton activated carbon. Every three tanks are one group, in which, two tanks are used for adsorption, and another one is for desorption.
Tank size: Diameter 3meters, Length 7meters.
Desorption times：3-5 times
Desorption time： 90-100mins
The desorption temperature:110 degrees
When the raw material of tape goes into the tank, it will produce toluene. Activated carbon will adsorb and desorb toluene for recycling.
Conclusion of solvent recovery activated carbon
In the solvent adsorption recovery process, the recycling of activated carbon is important. Therefore, activated carbon must have excellent chemical stability, wear resistance, high adsorption capacity and low bed resistance. Zhulin Activated Carbon is specially designed for this application, and we provide special activated carbon with the best proven results. These activated carbons have high hardness, are not easy to pulverize, and can maintain stability and efficiency during long-term use.
The chemical stability of activated carbon ensures its long-term stable operation in various industrial environments, and its wear resistance extends its service life. High adsorption capacity means that a large amount of organic solvents can be effectively adsorbed, thereby ensuring efficient and cost-effective solvent recovery. In addition, low bed resistance helps reduce energy consumption and improve the operating efficiency of the system.
Zhulin Activated Carbon is committed to providing customers with reliable technical support and high-quality product solutions. If you have any technical questions or needs for activated carbon, please feel free to contact us, we will serve you wholeheartedly.
