Nitrogen Synthesis
• Air being around 78% nitrogen is a great place to get it.
• Air is then compressed and cooled, then transported to an insulated area
• The Nitrogen having a lower boiling point then the liquid oxygen is then
distilled out. Then compressed again without the oxygen.

Carbon Monoxide Synthesis
• Producer gas: CO2 + C → 2 CO (ΔH = −221 kJ/mol)
• Water gas: H2O + C → H2 + CO (ΔH = +131 kJ/mol)
• By product of Metal oxides: MO + C → M + CO

Carbon Dioxide Synthesis
• Side product of the industrial production of ammonia and hydrogen.
• Side product of fuel combustion (not normally recovered)
• Product of breathing
