Could everyone help me check if there are any issues with this process that don’t comply with the standards. This is an ammonia-based denitration project we are working on at the moment; nitrogen sealing is carried out using nitrogen seal valves. Safety valves and vent valves have been installed on the ammonia storage tanks. The exhaust gas from the safety valves should have been directed to a dilution tank, but for reasons that are unclear – whether it was to save money or to save space – the person who designed the system did not include such a dilution tank, and instead the pipes led directly into the wastewater tank (which is primarily used to store water used for industrial cooling and pipeline flushing). When the safety valves release gas in case of an accident, I think there are two types of gases: ammonia and nitrogen. Ammonia can be absorbed by the water in the tank, but nitrogen needs to break through the water seal; otherwise, the gas cannot be released. Therefore, there are specific requirements regarding the liquid level in the wastewater tank – it must be high enough to maintain the water seal, but not too high. For a wastewater tank that also stores other types of water, controlling the liquid level can be somewhat difficult. Another issue is related to this breather valve. Normally, the exhaust pressure of a breather valve should be lower than that of a safety valve. However, since it is a sealed container, this breather valve also needs to have the ability to break vacuum; therefore, it cannot simply vent air. I’ve seen some designs that use a water seal groove, which is a more complex approach, and it allows for both breathing functions to be fulfilled simultaneously. Now I’m thinking about whether it’s possible to set the exhaust pressure of the breathing valve higher, above that of the safety valve; in this way, the breathing valve could serve as the ultimate safety measure. Or, the breather valve could be made into a single-suction valve, so that only one safety valve is used for activation; it’s not clear whether this would ensure sufficient safety I hope those who have experience in this kind of design can offer some suggestions
