The gas driven off when low-grade coal is burned with

Chapter 13, Problem 13.21

(choose chapter or problem)

The gas driven off when low-grade coal is burned with insufficient air for complete combustion is known as producer gas. A particular producer gas has the following volumetric analysis: 3.8% \(\mathrm{CH}_{4}, 0.1 \% \mathrm{C}_{2} \mathrm{H}_{6}, 4.8 \% \mathrm{CO}_{2}, 11.7 \% \mathrm{H}_{2}\), 0.6% \(\mathrm{O}_{2}\), 23.2% CO, and the remainder \(\mathrm{N}_{2}\). For complete combustion with the theoretical amount of air, determine

(a) the molar analysis of the dry products of combustion.

(b) the amount of water vapor condensed, in lbmol/lbmol of producer gas, if the products are cooled to \(70^{\circ} \mathrm{F}\) at a constant pressure of 1 atm.
