Fractional distillation is the process by which oil refineries separate crude oil into different, more useful hydrocarbon products based on their relative molecular weights in a distillation tower. This is the first step in the processing of crude oil, and it is considered to be the main separation process as it performs the initial rough separation of the different fuels . [2]

2016-06-15· Crude Oil is useless until we separate this mixture using fractional distillation. The resulting fractions have different uses depending on their properties, and some fractions are more useful than others. In general, shorter chain hydrocarbons are more useful than longer chains. The majority of the use we get out of crude oil is as fuel.
