PSA 

PSA or Pressure Swing Adsorption is the process of separating liquid or gas parts from a mixture by adsorption and by the tendency of each molecule to adsorb in a different rate to an absorber. In this process after saturation of the absorber the adsorption bed is regenerated. The regeneration process is carried out by putting the bed under vacuum and an inert gas purge like nitrogen or carbon dioxide. The regenerated bed is then again used as an adsorption bed and the bed being under process is now shifted to regeneration mode.  With PSA equipment Parsian Green Chemical Industries Co. is able to dehydrate many industrial solvents as alcohols, esters, glycols, ethers, aromatics and many others to lower than 100 ppm in water content. We are also able to design and construct PSA equipment fitted to your needs.
