What is the best way to refine oil?

i think there is 2 way.chemical and heating.what is the best?What is the best way to refine oil?
Companies like Exxon, Shell and all the rest have been looking for this for 150 years. What sort of oil? Saudi Arabian? Texas? California? North Sea? Bass Strait? All these oil provinces produce different types of crude petroleum.





Then of course there are the original oils like olive oil, colza, fish oil and so forth which are all refined to some extent before sale, generally only by washing with clean water, drying, filtration and perhaps passage through charcoal.





There is no simple answer to this question. Not even a few simple answers. For petroleum, start with distillation under vacuum, then thermal or catalytic cracking of the heavy fraction, maybe reforming some of the lighter products. Every refinery will be built to produce a particular range of products from a small range of different inputs.What is the best way to refine oil?
The best way to refine oil would be distillation, they use a method of Fractional Distillation to break down crude oil into its different components.


you can look up fractional distillation on google..
distillation!!!!
Send it to a barrage of finishing schools
There is no particular ';best way';. it depends wat ur after. if ur after shorter chain carbons then go for catalytic craking. if u want to break the oil down completly then go for steam craking. Catayltic craking uses zeolites (aluminiosilicates) to speed up the process, and abt 500 degrees celcius, it breaks up the bonds up. steam craking is sending the oil through pipes and heating it so that it ALL breaks down. so depends wat ur after
