A fuel gas produced by gasifying coal is to be burned with 20% excess air. The gas contains 50.0 mole % nitrogen and the balance carbon monoxide and hydrogen. A sample of the gas is passed through an infrared spectrometer, which registers a signal R that depends on the mole fraction of carbon monoxide in the sample, and a reading R 38:3 is recorded. Analyzer calibration data are as follows: x (mol CO/mol) 0.05 0.10 0.40 0.80 1.00 R 10.0...

Methanol vapor is burned with excess air in a catalytic combustion chamber. Liquid methanol initially at 25 ◦C is vaporized at 1.1 atm and heated to 100 ◦C; the vapor is mixed with air that has been preheated to 1100 ◦C, and the combined stream is fed to the reactor at 100 ◦C and 1 atm. The reactor effluent emerges at 300 ◦Cand 1atm. Analysis of the product gas yields a dry-basis composition of 4.8% CO2, 14.3% O2, and 80.9%...

A fuel gas containing 75.0 mole% methane and the balance ethane is burned completely with 35.0% excess air. The stack gas leaves the furnace at 800.0°C and is cooled to 350.0°C in a waste-heat boiler, a heat exchanger in which heat lost by cooling gases is used to produce steam from liquid water for heating, power generation, or process applications. Take as a basis 100.0 mol of the fuel gas fed to the furnace. The amounts of each of the...
