The crude oil distillation unit (CDU) is the first processing unit in virtually all petroleum refiners. The CDU distils 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 atmosphere distillation unit because it operates at slightly above atmospheric pressure.
The incoming crude oil is preheated by exchanging heat with some of the hot, distilled fractions and other streams. It is then desalted to remove inorganic salts (primary sodium chloride).
Following the desalter, the crude oil is further heated by exchanging heat with some of the hot, distilled fractions and other streams. It is then heated in a fuel-fired furnace (fired heater) to a temperature of about 398° C and routed into the bottom of distilled unit.
The fractions removed from the distillation column at various points between the column top and bottom are called sidecuts. Each of the sidecuts (i.e. the kerosene, light gas and heavy gas oil) is cooled by exchanging heat with the incoming crude oil. All of the fractions are sent to intermediate storage tanks before processed further
