Case Study – A Durable Solution for the High – Pressure Carbamate Section in UREA Synthesis

A leading European UREA manufacturer encountered a persistent instrumentation issue involving pressure measurement with diaphragm remote seals on its high-pressure carbamate gas line—an environment known for its extreme conditions within chemical processing. Operating process parameters of up to 150 bar and 190°C and exposed to corrosive ammonium carbamate; traditional diaphragm seals typically had a service life of less than one year.
The customer required a dependable, corrosion-resistant method for installing a pressure measurement device near the safety valve — a location essential to optimizing reactor conversion but traditionally bypassed due to significant corrosion concerns.
