A synthesis gas at 500°C that analyzes 6.4% CO2, 0.2%O2, 40% CO, 50.8% H2, and the balance nitrogen is burnt with 40% dry excess air, which is at 25°C. The resulting flue gas, which exits at 900°C is cooled to 400 C in a heat exchanger to superheat saturated steam at 10 bar and 540 C.
In another heater exchanger the gas is cooled from 400 C to 150 C where water at 10 bar is preheated to 75C from 23 C. find out the steam and water quantities that are being heated?
