Issues with liquid ammonia storage tanks?
Thread Content
Are liquid ammonia storage tanks basically spherical? Why are spherical shapes chosen for liquid ammonia storage tanks?
The sphere handles forces well! Save steel, especially for large storage tanks!
I agree with what was said above – the main advantage is the excellent load-bearing capacity; in stress analysis, a spherical shape is the best choice. Additionally, the properties of liquid ammonia dictate that spherical tanks be used for its storage.
5 horizontal liquid ammonia storage tanks have been used, which are classified as Category 3 containers. Spheres are resistant to forces, save steel, but take up a lot of space.
The main issue is the frequent problems associated with liquid ammonia storage, coupled with the requirements of low-temperature storage; therefore, it is classified among liquefied hydrocarbons – pressure tanks. Spherical tanks are commonly used for storage, while vertical, double-wall tanks are employed for large-scale storage, and horizontal pressure tanks are used for smaller-scale storage.
What size of storage is considered large-scale storage?
Spherical tanks are used for volumes of 400 cubic meters or more
The one with a large volume is the spherical tank; the smaller one is not
Spherical tanks are only suitable for intermediate volumes; those with a volume exceeding 5,000 cubic meters should use double-walled flat-bottomed tanks
