Store Hot Naphtha into Ext. Floating Roof Tank
Store Hot Naphtha into Ext. Floating Roof Tank
(OP)
All,
What should I do for my storage tank (external floating roof type, which Working Press. is atm) if I will store hot naphtha(max. 50degC) at least 10 days without product cooler? Is the increment of RVP of hot naphtha will affect the tank?

in case you can not avoid,
1) low pressure/ATM API tank can operate 14 psi RVP if higher than this other type of tank shall appy. Please run the plant abit lower pressure/higher bottom temp than usual to improve lower RVP of product,. release more gas from distillation, RVP will improve but a bit flare loss
2) It will loss vaporize but not mean tank will damage since the liquid is from distillation column at bubble point and cool down by bare piping along from plant to tank, eventhough it has not enough cooling, 50 C still not so hot.
3) Breathing system of the floating roof already design for it.
4) Do not fill liquid higher than 70% of the tank during this period
5) run tank farm pump circulate time by time to gain cooling around network piping
