2050 L/hr of a mixture containing 25% methane, 35% ethylene, and 40% propylene at 49°C and 130atm is fed to an oven, where it is burned as fuel. This mixture is burned with 11,400,000L (STP)/hr and 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) Draw a process flow diagram of the process. (b) Calculate the molar flowrate of the entering gas fuel mixture. (C) Calculate the percent excess air

(a) Draw a process flow diagram of the process.
(b) Calculate the molar flowrate of the entering gas fuel mixture.
(C) Calculate the percent excess air
Given data:
Volumetric flow rate of mixture entering the oven = 2050 L/h
Temperature of feed = 49 0c
Pressure of feed = 130 atm
Volumetric flow rate of air = 11,400,000 L/h at STP
The composition of mixture is,
Methane = 25 %
Ethylene = 35 %
Propylene = 40 %
Temperature of stack gas = 0 0C
Pressure of stack gas = 1 atm
