Abstract:Problems existing in the trial run of 50 kt/a urea-process hydrazine hydrate facility were analyzed. The facility was built in a place under natural conditions such as high altitude, strong dusty wind, strong ultraviolet radiation, and large temperature difference between day and night. The problems included liner crack and deformation of equipment and pipes, blockage of sodium hypochlorite cooler, low yield of hydrazine hydrate, scaling in hydrazine hydrate reactor, and blockage of DBT crystallizer. Improvement were made to achieve the aims of smooth and long-period running of the facility, and all consumption figures and capacity approached design requirement.
Keywords:hydrazine hydrate  urea-method process  sodium hypochlorite  cooler  reactor  sodiumchloride  sodium carbonate
