What are some ways to remove water from oil, be it BIO, WMO, WVO....etc...

I have read of people mist drying it...

Can it simply be heated for a defined period of time? Other options?

I've read that centrifuges operated correctly will remove the contaminants and water in one step. Other, old way is to heat the oil and vent away water vapor. Some people use Magnesol which is what I am researching presently but don't have any yet to try.
