pour point and molecular weight of crude oil!

pour point and molecular weight of crude oil!

(OP)
Hello to all,

I need to use equations to calculate the pour point and molecular weight for crude oil if have idea please help me?

thanks

RE: pour point and molecular weight of crude oil!


Your question needs clarifying, do you mean predicting product properties based on lab crude assays ?

hi 25362,

infact I have sp.gravity and viscosity of crude oil and I need to use equations if it is possible to predict the pour point and molecular weight and make comparison between the two results. I hope my question is clear.

thanks

RE: pour point and molecular weight of crude oil!


I don't know of any valid algorithm to predict the pour or cloud point of petroleum oils as caused mainly by normal or slightly branched isoparaffins in the C20-C42 range, by using only gravity and viscosity.

For the relative molecular mass (molecular weight) one probably can get help from ASTM D2502-04. To characterize the crude, whether paraffinic or otherwise, one may use the VGC, viscosity-gravity constant.

For additional guidance you may visit some Google sites such as:
