What is the purpose of two small spherical tanks accompanying a large storage tank?
Thread Content
I have a technical question for my colleagues: We have a project involving an oil tank area, which includes 3 liquid ammonia storage tanks with a capacity of 20,000 m³ each (stored at normal pressure and low temperatures). The owner’s proposal is to equip these 3 tanks with 2 spherical tanks, each with a capacity of 1,500 m³. I don’t understand; what is the technical principle behind the owner’s approach? Could an experienced expert please explain this principle or what the purpose of doing this is? Thank you so much!
Small spherical tanks can be used as pressure buffer containers for storing liquid ammonia, to receive excess liquid ammonia when the pressure of the liquid ammonia in the large storage tank exceeds safe levels, or to supply liquid ammonia at low pressures in order to maintain stable operation of the system. It can also be used to separate and store gases discharged from large storage tanks, thereby reducing the impact on the environment. .
Should liquid ammonia be used directly or gaseous ammonia? If gaseous ammonia is used, it is pumped from a liquid tank at atmospheric pressure into the carburetor and then stored in a low-pressure tank for storing and buffering the gaseous ammonia
I have another question: How are these two pressure spheres connected to the 3 large full-volume tanks? Is it in parallel? Is it still the same as inverted tank processing – using an inverted tank production line?
