1 kmol of gas Ethane is burned with 175 percent theoretical air in a steady flow combustion chamber. An analysis of the combustion gases reveals that all the hydrogen in the fuel burns to H2O but 95 percent of the Carbon burns to CO2 with the remaining 5 percent forming CO. Treating the air as dry air, determine; (a)The balanced combustion equation. (b)The air-fuel ratio. (c)The amount of heat transfer (in kJ/kg of fuel) from the combustion process if the...

. (5pt) Ethylene oxide is produced by the catalytic oxidation of cthylenc C3H4 + O2 → C2H40 An undesired competing reaction is the combustion of ethylene CO2 + H2O C2H4 + O2 The feed to the reactor contains 4 moles of ethylene per mole of oxygen, while the oxygen contains 0.4% inerts. The single pass conversion of ethylene is 15% and for every 100 moles of ethylene consumed in the reactor, 80 moles of ethylene oxide emerges in the reactor...

1. Acrylonitrile is produced by the reaction of propylene, ammonia, and oxygen C3H6 + NH3 + O2 C3H3N + 3H2O The feed contains 10 mole% propylene, 12% ammonia, and 78% air. A fractional conversion of 30% of the limiting reactant is achieved. Determine which reactant is limiting, the percentage by which each of the other reactants is in excess, and the molar flow rates of all product gas constituents for a 30% conversion of the limiting reactant, taking 100...

Combustion of hydrocarbons such as ethane (C2H) produces carbon dioxide, a "greenhouse gas." Greenhouse gases in the Earth's atmosphere can trap the Sun's heat, raising the average temperature of the Earth. For this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide. 1. Write a balanced chemical equation, including physical state symbols, for the combustion of gaseous ethane into gaseous carbon dioxide and gaseous water 2. Suppose 0.150 kg of...
