Combustion of Ethane: Stack Gas Molar Composition

Ethane is burned with 50% excess air. The percentage conversion of ethane is 90%. Of the ethane burned, 25% reacts to form CO and the balance reacts to form carbon dioxide. Calculate the molar composition of the stack gas on a dry basis, and the mole ratio of water to dry stack gas.

Material balances for combustion of octane

One of the most common chemical reactors found around us is the car engine. It takes gasoline and reacts it with air to release chemical energy, which in turn is transformed into mechanical energy. Emissions from your car’s engine have been an environmental concern for many years. Using the concepts of material balances, determine how much (in moles and lbs) air is needed and CO2, N2, CO, and H2O are emitted for every gallon of gasoline burned in your car’s engine. Assume that gasoline, a mixture of many hydrocarbons, can be modeled as pure octane (C8H18). Assume that 90% of the octane is turned into carbon dioxide and water, and 10% of the octane is turned into carbon monoxide and ... click for more
