floating roof vs fixed roof 1

[hassann]

hello every body
what is the limitation for selecting the atmospheric floating roof storage tanks instead of fixed roof?
what is the limitation of atmospheric floating roof storage tanks with respect to flash point or vapour pressure or MW?

 

[LittleInch]

Usually about 10 or 11 psia vapour pressure

Apart from flash point is there any other parameter important for selecting floating roof storage tank?
