A fuet oil is fed to a furnace and burned with 35.0% excess air. The oil contains 88.0wt%C,9.00%H, and 3.00%S. Analysis of the furnace exhaust gas shows only N2,O2,CO2,SO2, and H2O. The sulfur dioxide emission rate is to be controlled by passing the exhaust gas through a scrubber in which most of the SO2 is absorbe in an alkaline solution. The gases leaving the scrubber (all of the N2,O2, and CO2, and some of the H2O and SO2 entering the unit) pass out to a stack. The scrubber has a limited capacity, however, so that a fraction of the furnace exhaust gas must be bypassed directly to the stack. At one point during the operation of the process, the scrubber removes 95.0% of the SO2 in the gas fed to it, and the combined stack gas contains 612.5ppm (parts per million) SO2 on a dry basis; that is, every million moles of dry stack gas (i.e. not including the water) contains 612.5 moles of SO2. Take a basis of 100.0kg of fuel oil. Assume air is 21.0 mole O2 and 79 mole %N2. How much O2 is required for complete combustion? kmol How many moles of O2 are actually fed to the furnace? kmol How many moles of N2 are fed to the furnace? kmol What mass of air is required for it to be in 35.0% excess? kg For the 100.0kg basis, calculate the number of moles of each of the following gases in the exhaust from the furnace. kmol kmol kmol kmol kmol
