ABSTRACT:
Sorbents used for drying organic liquid process streams can be regenerated by passing an organic liquid carrier solvent such as n-octanol therethrough at a temperature sufficient to dissolve water trapped in the sorbent, thus regenerating it, and subsequently cooling the organic liquid carrier solvent/water solution such that it separates out allowing recycle of the organic liquid. This method of sorbent regeneration allows the use of low grade heat for regeneration thus improving the viability of sorbent drying plant.
