The ethane oxidation reaction is described by the following chemical reaction equation.
2C2H6 + 7O2 = 4CO2 + 6H2O;
According to the coefficients of this equation, 7 oxygen molecules are required to oxidize 2 ethane molecules. In this case, 4 molecules of carbon dioxide are synthesized.
Let’s calculate the amount of ethane available.
To do this, we divide the available gas volume by the volume of 1 mole of ideal gas under normal conditions.
N C2H6 = 17.92 / 22.4 = 0.8 mol;
The amount of oxygen will be.
N O2 = 0.8 x 7/2 = 2.8 mol;
Let’s calculate the gas volume. To do this, multiply the amount of substance by the volume of 1 mole of gas.
Its volume will be: V O2 = 2.8 x 22.4 = 62.72 liters;
Taking into account the oxygen content in the air of 21%, the required air volume will be:
V air = 62.72 / 0.21 = 298.667 liters;
