Felder & Rousseau (Elementary principles of chemical processes) Example 8.3-5 Gas Preheater 20 o C 1 atm 2000 standard liters/min 10 mole% methane 90 mole% air 300 o C Q kW A stream containing 10% CH 4 and 90% air by volume is to be heated from 20 o C to 300 o C. Calculate the required rate of heat input Q in kilowatts if the flow rate of the gas is 2.00 X 10 3 liters (STP)/min Solution by hand calculation: Heat capacity data is often expressed in polynomial form: i=O 2 , N 2 , CH 4 where
