A stream of methane at 120.90 kg/hr is burned in a boiling tank. The boiler is fed 37.30 % air, in excess. Solve for the water composition of the flue gas (wet basis), in mass percentage. Air can be treated to be 78 % N2, 21 % O2 and 1% Argon, where all percentages are in mole percents. The average molecular weight for air of this composition is 28.97 kg/kgmol

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 NO, 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 waste gas stream, containing 15 % CO2,5 % H2S, 1.5 % Co, and the balance is CH4 by mass, is leaving a chemical process. H2S and CO have to be removed from the waste gas stream due to severe environmental concerns. An absorber is installed so that H2S and CO in the waste stream can be removed before being released to the environment. The absorber design placed a maximum flow rate limit of 75 kg/h. Therefore, any feed flow...

Question 2 A feed material stream flowing at a rate of 100 kg/h is fed to a distillation column. The feed contains 45 wt.% benzene (C6H6) and the remainder toluene (C6H5CH3). The distillate stream contains 98 wt.% benzene. The bottom stream contains 10 wt.% of the benzene fed to the distillation column. a) Draw a block flow diagram of the process and annotate appropriately with the data provided, state the basis and define variables for unknown flow rates and compositions....

A mixture containing 42% benzene and 58% toluene by mass is fed to a distillation column. A second mixture is also fed to the distillation column and has a composition of 65% toluene and 35% acetone by mass. The flowrates of the mixtures are 2500 kg h1 and 1500 kg h1 respectively. An overhead distillate exit stream of 800 kg h-1 containing 23% acetone and a bottom exit stream of 25% benzene are produced. Determine the bottom exit flowrate and...

A natural gas containing 82 mole% CH, and the balance C2H6 is used as a fuel to generate steam in an industrial plant (Figure 2). The natural gas is fed into a furnace at 25°C and burned at a rate of 10.000 mol/hr with 20% excess air. The heat transferred from the furnace is used to convert a liquid feed water at 25 °C into a saturated steam at 30 bar. During the combustion of natural gas, all the CH,...

90% of pyrite conversion was achieved with 50% of FeS2 converted to form sulfur dioxide while the rest forming sulfur trioxide. 100 kg/hr of ore was roasted with 200% theoretical air. The solid waste stream contained the unconverted pyrite, ferric oxide, and inert. The gas stream exits the furnace is cooled from 1000°C to 545°C at a constant absolute pressure of 35.0 atm in a waste-heat boiler. Determine the composition of the gas stream, the mass ratio of the solid...
