ABSTRACT:
A more economical method of removing materials adsorbed on solid adsorbents used to treat hydrocarbon streams is presented. The method comprises removing a liquid hydrocarbon stream from a distillation column, vaporizing the liquid stream and superheating the vapors which are formed, passing the superheated vapor through the adsorbent and effecting the removal of the adsorbed material, and then returning the vapor to the fractionation column and utilizing the vapor as stripping media within the column. In the preferred embodiment, water is removed from alumina.
