Question: 2050 L/hr of a mixture containing 25% methane, 35% ethylene. and 40% propylene at 49 °C and 130 atm is fed to an oven, where it is burned as fuel. This mixture is burned with 11,400,000 L (STP) /hr of air at STP conditions. The mixture undergoes 100% conversion and complete combustion. The stack gas exits at a pressure of 1 atm and a temperature of 0°C.
(a) Calculate the molar flowrate of the entering gas fuel mixture (Hint. Use generalized compressibility chart and pseudocritical values from Table B.1 of book: For isopentane. look under pentane to find)
(b) Draw a process flow diagram of the process
(c) Calculate the percent excess air.
(d) Calculate the volumetric flowrate and molar composition of the exiting gas stream (dry basis).
(e) Calculate the volumetric flowrate and molar composition of the exiting gas stream (wet basis).

The assignment is about material balance and process calculation for fuel combustion. Hydrocarbon is burned entirely and converted to carbon dioxide and water. Complete burning of hydrocarbon requires an excess amount of oxygen. The assignment tells input rate of hydrocarbon, oxygen, and output of carbon dioxide production rate in fuel combustion chamber.
