The material of the storage tank is generally selected from low-alloy pressure vessels such as Q345R and 16MnDR, with low-alloy plates. The design pressure is taken as the gas saturation vapor pressure at 60 ℃, and the volume is generally 25~100m3, with a filling coefficient of ≤ 0.95
In industry, liquid ammonia storage tanks are used to store liquid nitrogen. Based on the relevant characteristics of liquid nitrogen, there are some things to pay attention to when using storage tanks to ensure storage effectiveness and safety. When using liquid ammonia storage tanks, it is necessary to ensure that the inner cavity of the tank is cleaned once a year to prevent liquid nitrogen from corroding the pipe wall.
Before cleaning the storage tank, the liquid nitrogen in it should be discharged and cleaned according to the method. Then, neutral detergent should be used for cleaning work. After cleaning with detergent, a large amount of clean water should be used for secondary flushing. The storage tank cannot be put into use immediately after cleaning. It is necessary to ensure that the moisture inside the tank is controlled dry. At the same time, attention should be paid to the temperature of the detergent and flushing water, because the liquid nitrogen storage tank stores liquid nitrogen and requires low temperature requirements. Therefore, the temperature of the cleaning liquid should generally not exceed 40 degrees Celsius. If the temperature is too high, it will affect the performance of the storage tank.
