An engineer is sizing an ammonia tank to provide 30 days storage of NH3 for an SCR system. The furnace flue gas flow rate is 100,000 SCFH (standard cubic feet/hr) on a dry basis. The NOx reduction required in the flue gas is 30 ppm on a dry volume basis. Calculate the NH3 tank size in total SCF (standard cubic feet) of NH3 storage required for 30 day supply of NH3 assuming the flue gas flow rate and NOx concentration remain constant and NH3 is injected on a 1/1 NH3/NOx volume rate.
