Api-650 is applicable to atmospheric storage tanks while Api-620 is applicable for storage tanks up to 15psig pressure.

 

Regards.

the selection of tank for storage may consider of following :

 

1. The properties of the material to be stored. For example : RVP

2. Is the liquid material a finished product or intermediate product which need for further process. For example for reformate (intermediate product).

    Even having low RVP, it is normally stored in a tank with internal floating roof, blanketing with Nitrogen, to prevent contacting with Oxygen (prevent oxidation or oxygen dissolved).
