Engineering Thermodynamics The distillation carried out in such a way that the liquid with the lowest boiling point is first evaporated and re-condensed, then the liquid with the next higher boiling point is then evaporated and re-condensed, and so on until all the available liquid fuels are separately recovered in the sequence of their boiling points. Such a process is called Full distillation Fractional distillation Carbonisation Cracking Full distillation Fractional distillation Carbonisation Cracking ANSWER DOWNLOAD EXAMIANS APP
