The synthesis section of a urea plant is core to produce Urea. 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. The steam requirement and thereby the operating costs are much less than with other alternatives
LESER has designed three types fulfilling the requirements subject to the application specification.
With more than 900 employees, LESER is the largest manufacturer of safety valves in Europe and a leader in its market worldwide. LESER is able to supply all your safety valves for your complete fertilizer complex (ammonia, urea, nitric acid, utilities, etc).
