wax formation
(OP)
Hello,
Is there a method that can help determine the quantity of wax precipitates in the crude oil in given pressure and temperature conditions? Provided that fluid composition is known.
Thank you.

RE: wax formation
I don't know of a way to "predict" the amount of precipitable waxes, however, I think the lab could carry out quantitative solvent dewaxing trials (as for lubes) upon chilling to a predetermined temperature, on three or more fractions obtained by distillation. Filtered waxes would be washed with sufficient solvent for the practical removal (i.e., deoiling) of any trapped or occluded oils.
Ketones are excellent for the job with lubes.

The link to the site used to be www.dbra.com, however it seems that they are now owned by Schlumberger as the website is changing. Use google and DB Robinson wax gives you more info.
Good luck.
