urea production

[bastean]

Urea is produced with ammonia and carbon dioxide. Could the C02 from burning coal be dealt with through urea production for fertilizer?

CO2 is CO2. The only issue is the cost.

The problem is that the Urea process is a high pressure process. This would require recovering high purity CO2 from the flue gas and then compressing it.

The plant I worked at recovered the CO2 from an hydrogen reformer and then later as liquid CO2 from an outside vendor.

CO2 is a by-product of ammonia production. that is why you see urea plants paired with ammonia plants.
