Question 6 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 8 lb

hexane per 100 lb carbon under the conditions at which the system will be operated (net adsorption). If the system is to operate at 90 oF and 1 atm and flow velocity of 100 ft/min, determine the mass of carbon (in lb). Bed regeneration and cooling will require one hour. Assume carbon density is 25 lb/ft³. The bed depth should be at least 1 ft. Add your answer Integer, decimal, or E notation allowed 8 Points
