Abstract
A system and method of reactivating wet spent activated carbon comprising a batch operated solid-liquid separator, a continuous feed electrically heated furnace and surge bin therebetween. Heat exchangers recover sensible heat of the exhaust gases and/or hot carbon leaving the furnace to heat the air used by the solid-liquid separator. A portion of the furnace exhaust along with added air is recirculated through the furnace to provide the appropriate atmosphere for regeneration of the carbon.
