Show the process-flow diagram Blue water gas (BWG) is obtained by passing steam over red hot carbon-enriched coal. The gas is called "blue" water gas due to the blue flame associated with the process, a characteristic of the combustion of CO. A typical composition shows 4.9% CO2, 40.8% CO, 49% H2, 0.9% CH4, and 4.4% N2. Blue water gas at 23°C, 748 mmHg, and 90% RH is burned in wet air, supplied 30% in excess at the same conditions as the blue water gas at 85% RH. The molar ratio of CO, to CO in the flue gas is 1:8. Calculate: a) Orsat analysis of the flue gas b) m' air/m BWG c) m flue gas (at 100 kPa, 300°C)/100 moles of BWG
