ABSTRACT:
An apparatus and process for removing impurities from silicone based solvents is presented. The apparatus and process use an adsorbent for removing contaminants from the solvent, and when the adsorbent is sufficiently loaded with contaminants, the adsorbent is regenerated. The regeneration process entails a two stage heating process for recovery of solvent and removal of contaminants.
