30%, haha – is your raw material supply just oil mixed with water? For crude oil dehydration, simple distillation can be considered: the distillate from the top is allowed to settle and lose water before being mixed back with the oil from the bottom.
Previously, before performing distillation at the actual boiling point, we would place the barrels containing crude oil in a water bath, with a condenser used for reflux; sometimes it took 2 or 3 days in such a water bath to achieve the desired result. Now, the distillation apparatus for the actual boiling point can handle crude oil that contains water
