Petroleum Products from Distillation Column: Visit weldfabworld.com 1💫Fractional distillation separates a mixture into “fractions” based on different boiling points; in refineries, crude oil vapor enters a tall column with trays/packing where vapors condense at levels matching their boiling ranges. Lighter fractions have fewer carbon atoms and lower boiling points; heavier fractions have more carbons, are more viscous, and condense lower in the column. 2💫Main products and typical uses ➡️Refine
