To increase production, it is necessary to raise the volume of gas in the system under appropriate gas composition conditions, or to reduce leaks. The liquid level in the intermediate tank has little impact; a higher liquid level may lead to slightly more flashing. Avoid excessive pressure reduction, and then there should be no problems
Without any leaks, the amount of ammonia produced will be equal to the amount of gas present; however, this ammonia includes both the liquid ammonia stored in the tanks and the ammonia used by the system； The use of ammonia in the system cannot be ignored; for example, ammonia is used in copper cleaning systems, and it is also required to remove carbon dioxide from carbonization systems. In all these cases, there is a risk of ammonia loss, especially in the carbonization process. If the operations are not carried out properly, it can have a significant impact on the ammonia production during that shift.
The ammonia production is affected by many factors: 1 the gas composition of the feed gas; 2 the system circulation volume; 3 catalyst activity; 4 temperature and pressure; 5 the liquid level in the ammonia separator also has an impact. If the liquid level is high, the separation of ammonia is poor or the gas contains ammonia, resulting in a high ammonia concentration at the inlet of the synthesis tower, which affects the ammonia reaction and thereby reduces ammonia production
