You are in charge of a combustion furnace. The furnace is fed an air stream and a methane stream which is combusted to produce heat that is used to boil water and produce steam for your plant. The combustion of fuels using an air stream which contains nitrogen generally produces significant amounts of NOx compounds which are an air pollutant, so the exhaust gases must generally be removed through various processes. In this case, your furnace exhaust is passed through a "wet scrubber" in which the gas is contacted with a water stream which absorbs the NOx compounds and that scrubber effluent stream is sent on for further treatment where the nitrogen compounds can be removed through conversion to harmless forms. 5. The scrubber removes all of the NO2 from the furnace exhaust and enough water is fed to the scrubber so that the concentration of NO2 in the scrubber effluent stays at 2mol% (i.e. if the concentration of NO2 were to get too high it would exceed the solubility limit and all of the NO2 would not be removed from the exhaust and it would be sent out the stack). Assume that CO2 is not soluble in the water. 6. The exhaust gas is so hot from the furnace that 5% of the water stream fed to the scrubber is evaporated to form steam and that all of the water formed in the combustion reaction in the furnace also remains as steam which is sent out the stack as water vapor
