Application-based safety valves for urea plants

The synthesis section of a urea plant is core to produce urea with safely and with high on-stream times. The safety valves applied in this section must be resistant to the high corrosiveness and the tendency to crystallisation of the carbamate to be processed. The LESER Urea Synthesis Safety Valve sets in at these key requirements for the synthesis process.

  • The selection of the materials is exactly optimized for the critical application and guarantees the corrosion resistance.
  • The unique continuous steam purging (LESER Flush) design prevents the condensation and crystallisation of the carbamate during normal operation and during blow-off conditions. No need to service the safety valve after blowing off.
  • The steam requirement and thereby the operating costs are much less than with other alternatives.
  • With the LESER Support Loading System Technology significant higher synthesis operating pressures and related higher conversion figures can be realised while realising 75% less emissions during a blow off situation.
