Matlab -- developing 22 independent material balances and solving in Matlab

Please see attachments. One attachment contains instructions and an illustration of the system we're dealing with. The other attachment shows how the material balances were set up in a matrix and developed into a Matlab program that solved for composition and flow rates of each stream. What I would like you to do is show me how to set up and solve these 22 balances by hand (using the mass percents and feed flow information given), and please include a description of all the variables used, along with their units. I need to solve these balances by hand so I can check that the Matlab program is working properly. How do I know I will be able to set up 22 independent balances? What makes t... click for more

combustion of ethane

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
