Graph of Common Petroleum ProductÆs Viscosity verses Temperature

[CRG]

I used to have a graph showing viscosity of the most common petroleum products verses temperature and now I can’t find it. Does anyone know where there is something like this on the internet? Specifically, I am looking for a relationship of viscosity verses temperature for Ultra Low Sulfur Diesel (ULSD) at -20 to -50 degF.

since there is no such thing as a standard Ultra Low Sulphur Diesel composition, just use any old diesel table.

I use the GPSA Engineering data book Fig 23-21 for my viscosities.

dcasto,

Thank you for the information and the reminder that fuel oil properties are dependent on the specific market and refiner. After reading your reply, I have contacted the refinery that is producing this product to get the information on the Arctic grade ULSD that they market.

Thanks for your help.

Suggest you invest in Chempak by AFT

http://www.aft.com.

This has over 700 materials available with up to 15 properties. These properties can be determined at a range of temperatures. Also mixtures can be modelled. Cost is relatively low for the information available. Download the the demo. There is also an Excel interface.

Ingersoll Rand's Cameron hydraulic pump handbook has a bunch of curves for viscosity of various materials versus temperature.

Depending where you work a lot of the older pump catalogs used to also provide this information.

You'll find out that lots of hydrocarbons tend to (but not always) follow similar sloped curves so if you have the viscosity at one temperature you can predict it at another temperature. With diesel and heavier hydrocarbons, things can cloud points can keep you from extrapolating too far.
