Term: Carbonation
Urea Production:
– Carbonation of ammonia is a step in urea production.
– Worldwide production capacity in 2020 was around 180 million tonnes.
– Urea is a nitrogen source for plants.
– Urea production plants are typically near ammonia manufacturing sites.
– Ammonium carbamate decomposes into urea, releasing water.
Solubility:
– Henrys law relates CO2 gas pressure to its solubility.
– Henrys law constant increases with temperature.
– Carbonation increases as temperature decreases.
– Carbonation involves converting CO2 gas into carbonic acid.
– Decreased CO2 pressure or increased mole fraction in solution supports carbonation.

Carbonation is the chemical reaction of carbon dioxide to give carbonates, bicarbonates, and carbonic acid. In chemistry, the term is sometimes used in place of carboxylation, which refers to the formation of carboxylic acids.
In inorganic chemistry and geology, carbonation is common. Metal hydroxides (MOH) and metal oxides (M'O) react with CO2 to give bicarbonates and carbonates:
- MOH + CO2 → M(HCO3)
- M'O + CO2 → M'CO3
