Method for determining the wax content in petroleum products

Thread Content

I have a question for everyone: have you ever measured the wax content in the side products obtained from atmospheric and vacuum distillation? What method is used to determine the wax content in side-stream products? Could you share what the specific standards are?

The solvent dewaxing method is employed: the oil is dissolved using a mixture of toluene and butane as solvents at low temperatures, after which the temperature is lowered to -20 degrees. After 30 minutes, filtration is carried out to obtain the filtrate, from which the solvent is then distilled off.

Shouldn’t it crystallize at low temperatures, wax?
