High ammonia content after the saturator
Thread Content
The ammonia content in the saturator gas has suddenly increased; what aspects should be considered to find the cause?
Whether the acidity of the mother liquor is too low, whether the temperature of the mother liquor is normal, whether the secondary spraying pump is operating properly, whether the mother liquor circulation pump is functioning correctly, and whether the ammonia content in the gas before the reactor is within normal limits, etc.
At present, the ammonium sulfate production unit consumes approximately 3.8 tons of coker desulfurization and denitration waste liquid per day on average
Then it is even more necessary to check whether the spraying system is working properly, as there is a possibility of clogged nozzles. The acidity and impurities also need to be checked
Check whether the temperatures of the gas and mother liquor are appropriate, whether the circulation rate of the main mother liquor pump is normal, whether there is any damage or blockage in the large and small mother liquor nozzles, whether the acidity of the mother liquor is suitable, as well as whether the gas volume is high and the flow rate is fast. The saturator resistance is too high. The crystal ratio is too high. Gas short circuit inside the saturator, etc
It should be checked on the equipment: the large and small mother liquor nozzles, as well as any corrosion or short circuits inside the saturator
