Emergency venting petroleum products

[Okey1]

I am sizing emergency venting for storage tanks for petrol, Kerosene, AVgas and Gas Oil according to EN14015:2004.

I would be glad if any one can point me in the right direction where i can get information on the following for the products

1. Molecular weights
2. Heat of vaporisation
3. boiling temperature

Petrol, gas-oil etc. are generic terms, in my opinion you would need less generic values for mw, hv, bp when sizing a relief device (or you may adopt predefined values with some safety factor).

What is exactly your responsibility in this? Are you working for a E&C firm or for an operator? One would think that the process engineers of the site/plant/firm will be able to give you the required data. Or you could ask for lab results.
