Pressure increase in the acidic gas separation tank
Thread Content
Our company uses single-tower high-pressure side-line extraction; part of the ammonia gas separated out has to be sent to a combustion furnace for burning. Now, the ammonia pipeline leading to the combustion furnace does not go directly into the furnace; instead, it merges with the pipelines coming from the acidic gas separation tank before entering the combustion furnace together. As the ammonia is introduced for a longer period of time, the pressure inside the acidic gas separation tank increases. Is this because ammonia pushes the acidic gas back? Also, the pressure in the acidic gas separation tank rises more rapidly at night than during the day. Why is that? I ask for the guidance of all teachers!
When ammonia is mixed with acidic gases, ammonium salts are formed before sulfurization. What is the temperature of your acidic gas in the sulfur production furnace?
Ammonia and acidic gases can form ammonium salt crystals that cause blockages at low temperatures; try installing heating, and increase the intensity of that heating

At night, the pressure in the acidic gas separation tank rises more rapidly than during the day; this is probably because the temperature is lower at night, allowing crystals to form more easily and thus accelerating the crystallization process
