Question

Producer gas has the following composition by volume: O2 . The oxygen fed from the air and the producer gas is 20% in excess of 68.0 1.2507 2CO + O2 2CO2 The oxygen is from the air whose volumetric composition is assumed to be 80% N2 % Density, kg/m3 The gas is burned with oxygen according to the following equation: CO2 3.5 1.9768 the amount required for complete combustion. The combustion is 98% complete. N2 CO 28.0 1.2501 0.5 1.4289 and 20% O2 Carry out total material balance for this process based on 100kg of gas burned.​

Answer 1

To solve this problem, we need to balance the equation, convert the mass of CO, O2, and CO2 to moles, determine the moles of oxygen required, calculate the excess oxygen available, and determine the percentage composition of each gas component.

Step-by-step explanation:

The student is asking for a total material balance for the given process based on 100kg of gas burned. To solve this problem, we need to balance the equation first.

From the equation: 2CO + O2 → 2CO2

• The molar mass of CO is 28.0 g/mol
• The molar mass of O2 is 32.0 g/mol
• The molar mass of CO2 is 44.0 g/mol

Based on the molar masses, we can convert the mass of CO, O2, and CO2 to moles and calculate the moles of each substance.

Next, we determine the moles of oxygen required for the reaction and calculate the excess oxygen available.

Finally, we can calculate the total moles of gas in the system and determine the percentage composition of each gas component.
