Refining and Distillation
is method of chemical engineering and altered with accessories acclimated in which can help to convert crude oil into useful products such as (LPG), , , , and . Usually is heated and converted into. The are flow into the bottom of a and became cooler as they move up to the height of column. As the cool below their boiling point, they get condensed into liquid. The liquid are then flowed into at certain heights, ranging from heavy residues at the base, raw in the mid-sections, and raw at the top. These fractions are then processed to make several various finished product.
The fraction of found to be uses overall, the highest demand is for. The of one barrel contains 30-40% . Transportation demands acquires over 50% of the be transformed into gasoline. Due to this demand some converted into .
This techniques was determined by breaking down greater molecules of heavy heating and resides; retransforming the molecular structures of low quality molecules; then the isomers reorganising the atoms in a molecules due to that the product has same chemical formula but difference in structure, such as converting normal butane to isobutane.
