A Crude Distillation Unit (CDU) is the first processing unit in all petroleum refineries that operates an incoming crude oil into various fractions of different boiling ranges, and then processed further in the other refinery processing units, treated and transformed into marketable products like gasoline, diesel, jet fuel, and other refined products. A CDU is heated to 350 ~ 400°C and the vapour and liquid are piped into the distilling column that is often referred to as the Atmospheric Crude Distillation.
