    • Formaldehyde from Methane - Extent of Reaction, Atomic Balance - Example Page

      2021-37-pc

      Formaldehyde is produced by the oxidation of methane in a reactor. The following two parallel reactions occur. \[ \begin {align*} \ce {CH4} + \ce {O2} &\rightarrow \ce {HCHO} + \ce {H2O} \\
      \ce {CH4} + \ce {2O2} &\rightarrow \ce {CO2} + \ce {2H2O} \end {align*} \]
      Methane and oxygen are fed to the reactor. The product gases leaving the reactor include methane, oxygen, formaldehyde, carbon dioxide and water vapor.

      60 mol/s of methane enters the reactor. The molar flow rate (in mol/s) of \(\ce {CH4}\), \(\ce {O2}\) and \(\ce {CO2}\) leaving the reactor are 26, 2 and 4, respectively. The molar flowrate of oxygen entering the reactor is ________ mol/s.

    • Combustion of Propane: Atomic Balance - Extent of Reaction - Workout Page
      1990-11-i-pc

      Pure propane (\(\ce {C3H8}\)) is burnt with an excess of air to give the following analysis of combustion products in volume percent:

      \(\ce {CO2}\) = 5.0, \(\ce {CO}\) = 3.5, \(\ce {H2O}\) = 11.4, \(\ce {O2}\) = 7.0 and \(\ce {N2}\) = 73.1
      Calculate the percentage of excess air used.

      Felder3E-4-71

      Liquid methanol (density = 792 g/L) is fed to a space heater at a rate of 12 L/h and burned with excess air. The product gas is analyzed and the following dry-basis mole percentages are determined: \(\ce{CH3OH}\) = 0.45%, \(\ce{CO2}\) = 9.03%, and \(\ce{CO}\) = 1.81%.

      1. Calculate the percentage conversion of methanol ______ , the percentage excess air fed ______ , and, mole% of water in the product gas _______.
      2. Calculate the molar flow rate of dry product gas (i.e., excluding water vapor) ______ mol/h, and that of water vapor ________mol/h.
