Active carbon systems are used to recycle solvents arising from packaging, serigraphy etc. sectors. Solvent recycling is the process in which solvents in gas emissions filtered and adsorbed via columns containing active carbon and then regenerated with a hot fluid(steam or nitrogen).
If solvents do not resolve in water, steam regeneration is a preferred method. Because its condensation, cooling and separation from the solvent to be recycled is easier.
For the regeneration of pollutant materials resolving in water or resolving partially and the regeneration of the solvent to be recycled nitrogen is used.
Installations are equipped with auxiliary systems to perform;
- Steam consumption reduction (economizer);
- Dewatering-Dehydration of recycled solvent
- Distillation of recycled solvents
