How can propylene in ink be recycled?
Thread Content
In our company’s screen printing process, we use acetone to clean the screens; so how can we conveniently recycle large amounts of acetone?
If the quantity is not large, use spherical activated carbon, which has an excellent adsorption capacity for hydrocarbon compounds.
http://bbs.hcbbs.com/viewthread.php?tid=511719 There are many companies on the forum that specialize in recycling waste solvents; if the quantity you have is small and it’s in liquid form, you might consider turning to them. In the case of meteorological applications, for example, in the printing industry where large amounts of organic VOCs are emitted during the drying of ink, it is necessary to design collection hoods through process calculations, and then recover these VOCs through adsorption, concentration, and condensation. If a relatively single solvent was used previously, then the recycled solvent can be used for reproduction.
