Engineering Homework Help

A fuel mixture containing 45 mol ethane (C₂H₆)/ h and 55 mol propane (C₃H₈)/ h is burned in a combustion reactor with 3700 mol air/ h (where air contains 21 mol% O₂ and 79 mol% N₂). The percent conversion of ethane is 63%, and the percent conversion of propane is 72%. In the reactor outlet stream, the molar ratio of CO₂:CO is 3:1. Use the Atomic Species Balance Method to solve this problem.

a) Draw a completely labelled flowchart for this process, including all known values and all unknown variables.

b) Perform a degree of freedom analysis for this process.

c) Calculate the percent excess air that is being fed to the com
