Like many chemical processes, also in urea plants pressure safety valves safeguard against too high pressures. Urea plants are however unique because the very corrosive and easy crystallizing ammonium-carbamate poses challenges to assure a safe and reliable operation of these safety valves. Passing safety valves can cause clogging of the outlet line and is a serious threat for safeguarding your equipment against too high pressures. Also loosing valuable ammonia and risking a negative environmental impact are related consequences. The synthesis section of a urea plant is safeguarded against too high pressures by synthesis safety valves. Operators prefer to operate the synthesis at a maximum operating pressure to realize a maximum conversion of ammonium carbamate into urea. But at the same time they need to be careful not to pop up the safety valves causing a major environmental impact and an unplanned expensive shut-down. This technical paper addresses abovementioned issues and presents the innovative BADOTHERM solution, which realizes a reliable and accurate measurement of the synthesis pressure and a detection method for passing safety valves. This solution can also be applied in other sections of a urea plant such as the recirculation section and hydrolyzer/desorber section.
