What causes the pressure buildup of ammonia at the inlet of a high-position ammonia absorber? What are some good solutions? Please share your ideas and suggestions.
Reason for pressure buildup of gaseous ammonia at the inlet of the high-position ammonia absorber: Is there crystal blockage at the gaseous ammonia inlet?； Is there a problem with the nozzle of the high-position ammonia absorber? ； Is there a problem with the liquid delivery volume of the circulation pump?
A few years ago, during a winter in our factory, something similar happened: in the carbonization workshop, there was pressure buildup at the inlet of one of the high-mounted ammonia absorbers. It took several days to identify the cause, and in the end, as no other solution was available, the ammonia absorber had to be disassembled, with the related pipelines taken apart one by one. It was then discovered that there was a blockage in the liquid-phase outlet pipeline (the water cooler) of the high-mounted ammonia absorber. I hope this information is useful to you.
One is that the water cooler is clogged, and the other is that the water cooler does not provide adequate cooling
Another issue is that the ammonia water pump either does not deliver liquid or the pressure is not high enough to meet the process requirements； Another extreme scenario is a low liquid level in the liquid ammonia tank, causing the vent gas to enter the ammonia cooling system.
May I ask if this ammonia absorber refers to the high-position ammonia absorber used for producing ammonia water?
Check whether there are any issues with the valve, such as its opening degree and valve head condition
Generally, it is due to a blockage in the ammonia gas pipeline or the ammonia absorber； The circulation volume of the ammonia water circulation pump is low ； Or it could be caused by an excessive amount of ammonia being supplied
