Show the block diagram of urea plant.

Question

Accepted Answer

The block diagram of a urea plant includes several stages such as synthesis, stripping, and granulation.

The synthesis stage involves the reaction of ammonia and carbon dioxide to form ammonium carbamate, which is then dehydrated to form urea.
The stripping stage involves the removal of excess ammonia and carbon dioxide from the urea solution.
The granulation stage involves the formation of solid urea granules through a process of spraying and cooling.
Other stages may include purification, concentration, and prilling.
The overall process is energy-intensive and requires careful control of temperature, pressure, and flow rates.
