Question

give a reaction to prepare urea FROM NH3.​

Answer 1

Explanation:

A mixture of compressed CO2 and ammonia at 240 barg is reacted to form ammonium carbamate. This is an exothermic reaction, and heat is recovered by a boiler which produces steam. The first reactor acheives 78% conversion of the carbon dioxide to urea and the liquid is then purified.
