A two-bed carbon adsorption system is to be designed to handle 8000 acfm of air containing 700 ppm of hexane. Laboratory studies indicate that carbon can adsorb 8lb hexane per 100 lb carbon under the conditions at which the system will be operated. If the system is to operate at 90 F and 1.0 atm at a removal efficiency of 99%, determine the approximate dimensions of each carbon bed. Bed regeneration and cooling will require one hour.
