| Abstract: | The operation of synthetic ammonia plant cold box and problems existed were described. The high pressure differential in the cold box was caused by improper filling of molecular sieve, poor filter and leakage of regeneration heater. Measures were taking, such as modifying filter cartridge, replacing molecular sieve, blasting purging of cold box, and optimizing molecular sieve operation, to ensure the steady pressure dif- ferential in the cold box, and good heat exchanging effect. |
