Vacuum Distillation Unit (VDU): further distills the residue oil from the bottom of the crude oil distillation unit. The vacuum distillation is performed at a pressure well below atmospheric pressure.
Fluid Catalytic Cracking Unit (FCC): under the action of heat and catalyst, upgrades the heavier, higher-boiling fractions from the crude oil distillation by converting them into lighter and lower boi...
Crude Oil Distillation Unit (CDU): is the first processing unit in virtually all oil refineries. The CDU distills the incoming crude oil into various fractions of different boiling ranges, each of whi...
Isomerization Unit: converts linear molecules such as normal pentane into higher-octane branched molecules for blending into the end-product gasoline. Also used to convert linear normal butane into is...
