Question

write manufacturing of urea chemical reaction.Also draw flow sheet for urea manufacturing​

Answer 1

Answer:

This is a two step process where the ammonia and carbon dioxide react to form ammonium carbamate which is then dehydrated to urea. ... In the process, ammonia and carbon dioxide are fed to the synthesis reactor which operates around 180-210oC and 150 bar pressure

Answer 2

Urea is manufactured by reacting ammonia and carbon dioxide in an autoclave to form ammonium carbamate. The operating temperature is 135oC and 35 atm pressure, the chemical reaction is an endothermic reaction and so ammonia is maintained in excess to shift the equilibrium towards urea formation.
