Furnace Is Used To Combust Hydrocarbon With Oxidizer To Produce Electricity For The Petroleum Refinery The Initial Mole 1 (134.05 KiB) Viewed 140 times

furnace is used to combust hydrocarbon with oxidizer to produce electricity for the petroleum refinery. The initial mole fraction of the oxidizer consists of 89 mol% of O2 and 10 mol % of N2. After the furnace, the flue gas mixture consists of CO2, O2, N2 and traces of NOx and SO2. The flue gas is sent to an absorption column to capture the SO2 prior to the emission. The combustion temperature in the furnace is 2000K. The molar density for the gas mixture is 2.4 x 10-6 mol/cm3. Assume the Zeldovich thermal mechanism is valid, propose the appropriate combustion time in order the discharged flue gas stream could meet the emission limit for NO (100 mg/m3). Suggest ONE (1) method to reduce the NOx emission from the above furnace. Justify your answer with explanation.
