Regarding the storage temperature of oil tanks

For example, the north is definitely different from the south; what parameters are related to the storage temperature? According to the new version of the petroleum storage code GB50074-2014, arch roof tanks can be used when the maximum storage temperature for aviation fuel is five degrees or less below its flash point. I’m stuck here – in the north, like in Harbin, there’s no problem, but my project is in the south. How can I determine the storage temperature? In the southern region, the maximum summer temperature is 38 degrees; with the sun shining directly on the oil tanks, what temperature can the oil inside those tanks reach? Experts, there is one main point that needs to be confirmed: I need to decide on the type of tank – a floating roof tank or an arch roof tank? The criterion is whether the maximum storage temperature is 5 degrees below the lightning threshold; it’s correct that it should not exceed 40 degrees, but is it required that it not exceed 33 degrees in specific locations? (The flash point of aviation fuel should be no less than 38 degrees.) Actually, there’s no problem with choosing a internal floating roof tank, but it’s an old factory and they don’t have the money for it. The existing ones are also dome tanks, and I’m thinking about whether it’s possible to make one as well.

In accordance with SH/T 3007-2014, sections 3.3 and 3.4, kerosene and jet fuel should be stored at temperatures of ≤40 degrees Celsius
Thank you for the reply; you are right. There is one main thing to confirm: I need to decide on the type of tank, an internal floating roof tank or an arch roof tank?

I think it could be considered as a vaulted tank. Set the storage temperature yourself to no more than 33 degrees. Activate the temperature interlock cooling water spray; cooling water should start to be sprayed once the temperature inside the tank reaches 30 degrees. Additionally, applying thermal insulation coatings to the storage tanks also has a certain effect.
If the existing dome tank can be used, isn’t it sufficient to install a floating disk? In this case, there’s no need to create something new; just make some modifications!
Thank you for the reply. I’ve thought about this plan too, but what if a fire breaks out right after the spraying is completed?
Thank you for your reply. The enterprise in the mountains has been using that oil depot for decades; this is the first time it’s being renovated. It took a full 6 years, from the preliminary studies to the construction plans. There’s no money available – we have to save every penny, cutting costs bit by bit
If the oil tank can still be used, we’re just grateful; who knows what might happen after any repairs are made. Moreover, the owner doesn’t agree to carry out those repairs.
