Problems with the storage and transportation of liquid ammonia
Thread Content
As the title suggests, what are the advantages and disadvantages of storing liquid ammonia at atmospheric pressure and under pressure? How can the problems of loading and downstream transportation of highly enriched material under normal pressure storage be addressed? Thank you
Storing under pressure is more economical when the volume is not large
Reheating is achieved through circulating water heat exchange or low-pressure steam heating using methanol as a carrier. Loading can be carried out by pressurizing the liquid ammonia with a pump and then reheating it; it is crucial to feed the gas phase into the ammonia compressor in order to prevent overpressure in the ammonia tank.
How should bulk purchased liquid ammonia be properly stored when unloaded into low-temperature, atmospheric-pressure tanks?
