The paper describes the step by step development and implementation of the Innovative Safety
Solution for Overpressure Protection in the Urea Synthesis.
The following benefits have been achieved: Increased safety & reliability, operating pressure closer to
the set pressure of the synthesis safety valve leading to higher conversion figures in the reactor; for
the design of new urea plants, the design pressure of the High Pressure equipment items can be
reduced leading to lower investment and longer inspection intervals.
