density of petroleum products density of petroleum products josy2020 (Chemical) (OP) 18 Jul 13 05:51 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 21121956 (Mechanical) 18 Jul 13 12:38 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. El que no puede andar, se sienta. RE: density of petroleum products zdas04 (Mechanical) 18 Jul 13 17:28 "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.

Nevertheless, have a look at thread491-82117: Generalized products density correction algorythms?? and thread481-97175: Diesel - Volumetric - Temperature differences for more comments.
