density of petroleum products

density of petroleum products

(OP)
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

RE: density of petroleum products

Hello everybody:

You can visit the site http://www.viscoanalyser.com/page8.html. This is, in my opinion, a good place for you to start. This site is recommended by a reputed member of this Forum jmw.

RE: density of petroleum products

"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.
