Hi, I want to know which standards are used to design the fire-water protection piping network in an oil storage farm. Thanks

I need information on regenerative desiccant dryers sizing. I couldn't find a book that talk about this subject. So please help me if you know any book!

Thank you for your great answers

we want to open a window or a door in the shell of a 220 ft diameter oil storage tank. what do the standards ( API650, API653) say about it and in what sections I can find it. the door si about a 6.5 by 6.5 ft and we want to open it so we can repair the tank's bottom.

I need to know the most important specifications and caracteristics of corrosion inhibitors that i need to demand from a contractor who is providing them to us. we need the inhibitors to use them in hydrostatic tests for oil storage tanks.

MJCronin, the Tank is not very old. It was built in 2002. the crude oil is Sahara Blend with a API gravity of 45° yes there was a protective inner coating and this repair is due to coating failure. the hole tank bottom is corroded and we are consedering a seconde bottom option we are planning...
