density of petroleum products 1

[josy2020]

Hello,
I am looking for an algorythm or an equation which i can use to convert density of petroleum products from physical temperature to 15oC.
Any help will be most welcome

"Petroleum Products" is such a messy term. Trying to convert crude from one temperature to another has to assume a staggering number of things about latent heats and boiling points. A stream that is liquid at -20°C is going to be very different at 15°C. Stuff that is a subcooled liquid at the first temperature may be a superheated gas at the second. Kinda changes density a mite. For a single-component liquid, you can use the bulk modulus to estimate at density at a theoretical temperature, but when you get a mix of Mother Nature's liquids it gets a touch more than complex.

There are waxy fractions solid at ambient temperatures. Nevertheless, have a look at thread491-82117 and thread481-97175 for more comments.
