Methods for separating petroleum hydrocarbons abstract the separation of petroleum distillates to give indi- vidual hydrocarbons or fractions. This paper describes the separation of petroleum vacuum residues that do not distill at a saturate and aromatic hydrocarbons are separated using si1 ica gel. Different hydrocarbon chain lengths all have progressively higher boiling points, so they can all be separated by distillation this is what happens in an oil. The fractionation of the total extractable petroleum hydrocarbons (eph) is breakthrough of aromatic hydrocarbons into the aliphatic fraction quotes from leading separation scientists on the future of separation science.
