Diesel Storage Tank: Vaporisation rate and Fire Relief
Diesel Storage Tank: Vaporisation rate and Fire Relief
(OP)
API 2000 enables one to calculate heat input to an atmospheric storage tank. If one has the boiling point at atmospheric pressure and the latent heat of the tank contents at that temperature, then one could calculate the vapour released and size the emergency vent. This is fine for liquids of known chemical composition, but how does one manage with No 2 diesel oil? What is the method for calculating vapour generation rates?





RE: Diesel Storage Tank: Vaporisation rate and Fire Relief
Alternatively, you could use the following arguement. Diesel is composed mostly of C10 to C22 hydrocarbons (I think I got this from the Chevron fuel webpages). You could use the lighter of those and use the chart I mentioned above to estimate the latent heat.
Then just make sure you put in a hatch or something with lots of extra capacity to account for the inaccuries in the above approach.
25362 or Art might have some better ideas also.

I shall proceed with the API approach. It is a new tank andd therefore a little but of conservative fat won't cause any harm.
