SOLVENT RECOVERY

DEC IMPIANTI offers various processes for treatment of gaseous emission bearing recoverable solvents (VOC), be it for economic, ecological or legislative reasons.

• ADSORPTION on activated carbon or hydrophobic zeolite and successive regeneration of the media to recover the adsorbed solvent through our exclusive processes:

1. DEC.RSV™ (thermal swing process - steam regeneration);
2. DEC.RSG™ (thermal swing process - inert gas regeneration - nitrogen);
3. DEC.RSG-E™ (thermal swing process - inert gas regeneration - nitrogen - complete of an economic and exclusive dehydration system, through molecular sieves);
4. DEC.RSG-V™ (pressure & thermal swing process - inert gas regeneration - nitrogen - complete of an economic and exclusive dehydration system, without molecular sieves);
5. DEC.RSX™ (thermal swing process - inert gas regeneration - nitrogen - complete of a new innovative and exclusive dehydration system, without molecular sieves);

We deliver also other winning technologies, like:

• DEC.ABS™:  (scrubbing), through the addition of a liquid and successive distillation of the mixture, thereby separating the solvent from the liquid used.
• AL.CRYoCON™: cryocondensation through liquid nitrogen of solvent stream.
