Fractional distillation a way to separate the liquid can evaporate from 2 or more with the same principles as conventional refining. To separate the components in the solution is to keep out of the way. But it is different from the conventional distillation is distillation distillation distillation, fractionation, suitable for use as a component of the solution to the boiling point a little differently. At this stage of the refining process, respectively. Most of the items in each section to condensation. Then distilled over and condensed steam steadily, which is comparable to a conventional distillation several times that the difference in the fractional distillation, distillation units. Column is By fractional distillation column will look into the complex layers while conventional columns are ordinary columns. No complicated column
