A multi-unit process first combusts propane and then removes water from the exhaust stream. The process is running at steady state. The company designing the process knows that they want to burn 60% of the propane (i.e. yield of CO; is only 60% of complete combustion of propane). The simple combustion reaction for propane is given below. Use the shortcut method to calculate the Degrees of Freedom around the Combustion Chamber.

Question
Transcribed Image Text:A multi-unit process first combusts propane and then removes water from the exhaust stream. The
process is running at steady state. The company designing the process knows that they want to burn
60% of the propane (i.e. yield of CO, is only 60% of complete combustion of propane). The simple
combustion reaction for propane is given below.
Use the shortcut method to calculate the Degrees of Freedom around the Combustion Chamber.
