Abstract:In order to accurately calculate the ammonia storage content of horizontal liquid ammonia tank, this paper analyzed the gasliquid transformation rule of ammonia and the changing rules of gas phase pressure and liquid ammonia density in liquid ammonia tank, and proposed a calculation method of ammonia storage content according to the temperature, pressure and liquid ammonia level in liquid ammonia tank. The field application indicated that this method could accurately calculate the ammonia storage content of liquid ammonia tank, the consumption and unloading capacity of ammonia over a period of time, etc.
