Why is the medium in urea production plants highly corrosive to materials?
It’s probably because the raw materials contain ammonia, which corrodes the equipment during the production process
In the urea production process, the most corrosive substance is the ammonium carbamate solution. Additionally, the production takes place under high temperature and pressure in a gas-liquid two-phase state, and both high temperatures and intense erosion can cause severe corrosion to the equipment.
Corrosion-resistant materials can be chosen to reduce or prevent corrosion. Many of the current manufacturers of composite panels can meet the requirements
