The boiler in an apartment building uses propane (C3H8) to heat water that circulates throughout the building as steam. 1.00 m'/s of propane gas at 25°C and 1 atm is combusted with 10% excess air at 25°C and 1 atm. After all of the propane is combusted, the product gas contains a 10.0:1 molar ratio of CO2 to CO and leaves the boiler at 25°C. Heat from the boiler is transferred to a pure water stream at 50°C and 1.0 bar, which is converted into saturated steam at 20 bar, with no heat lost to the surroundings in the process.

The production of cement results in significant GHG emissions. The emissions are caused by the decomposition of calcium carbonate (limestone) to calcium oxide (lime) and carbon dioxide. This process known as calcination, is carried out in kilns. Therefore, additional GHGs are emitted as a result of heating the kilns. A large cement manufacturer uses a mix of coal, natural gas, and biomass in its boiler. This mix produces the following amounts of GHGs per Million BTUs of energy: • 250 lbs CO2/MMBtu • 5 lbs CH4/MMBtu • 0.36 lbs N2O/MMBtu Process carbon emissions from the calcination process produce 925 lbs of carbon dioxide per metric ton of cement. In addition, the plant uses 1.7 Million BTUs of energy per metric ton of cement. If the plant produces 180,000 metric tons of cement annually, how many metric tons of CO2e does it emit?
A 0.2m3 rigid tank initially contains pure oxygen gas (02) at 20°C and 1000 kPa. The tank containing the oxygen is put on a scale to measure its mass. The initial mass is recorded as 110.4 kg. Nitrogen gas is injected isothermally into the tank until the scale reads 121.0 kg. The molar mass of oxygen is 32kg/kmol and the molar mass of nitrogen is 28 kg/kmol. Assuming that the gases behave ideally, answer the following questions: a) What is the mass of the empty tank? b) What is the composition of the final mixture on a mole basis? c) What is the final pressure of the tank? d) The critical temperature and pressure of oxygen are 154.6K and 49.8atm. Based on these properties, comment on the appropriateness of using the ideal gas law in part a)
A process for the production of 1,3-butadiene results from the catalytic dehydrogenation at atmospheric pressure of 1-butene according to the reaction: C4H8(g) → C4H6(g) + H2(g), heat of reaction is 109780 J/mol. To suppress side reactions, the 1-butene feed stream is diluted with steam in the ratio of 10 moles of steam per mole of 1-butene. The reaction is carried out isothermally at 525°C, and at this temperature 33% of the 1-butene is converted to 1,3-butadiene. How much heat is transferred to or from the reactor per mole of entering 1-butene?
