Crude Oil Distillation Unit
Crude Oil Distillation Unit (CDU): cdu refinery 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 which are then processed further in the other refinery processing units. The CDU is often referred to as the atmospheric distillation unit because it operates at slightly above atmospheric pressure.
