A stream of 400 mol/min gases containing N2, O2, 1.85% H2O and 13.56% CH4 (all % mole basis) is combusted with 450 mol/min air containing N2, O2, 1.67% Ar and 0.72%  H2O. The exiting gaseous product contains CO2, CO, N2, Ar, H2O and O2 (only). After the water is completely removed from the exiting gas, the composition is found to be 1.01% Ar and 4.39% CO. i. What is the molar flowrate of H2O is the product? ii. What is the...

A gas has a dry-basis composition of 9 mol% CO, 10mol% CO2, 1mol% O2, and 80mol% N2. The gas temperature and pressure are 600°C and 1 atm and it has a dew point temperature of 50°C (due tothe presence of water). The gas must be cooled to 400°C. This is accomplished by spraying liquid water at 20°C into the gas.The liquid water evaporates and leaves the cooler with the gas as water vapour. Calculate the required volumetric flow rate of...
