Question

Identify the full form of CDU

A.Central distillation unit
B.Centre of distillation unit
C.Crude oil distillation unit
D.None of the these

Answer 1

Hint: We have to know that CDU is the first unit of processing in all refineries of petroleum. Petroleum refining processes are carried in refineries to transform crude oil into useful products like liquefied petroleum gas, petrol, jet fuel, diesel oil and fuel oils.

Complete step by step answer:
We must know that one of the most crucial and essential units in the petroleum industry is CDU.
The full form of CDU is crude oil distillation unit. It distills the incoming crude oil into a fraction of various boiling ranges. Each is then processed further into other refinery processing units.
They are commonly known as the atmospheric distillation unit since it functions above atmospheric pressure.
An oil refinery unit is a refinery unit, which separates crude oil into various materials based on their ranges of boiling point. The process of distillation permits the materials to be segregated without any conditions, which could cause cracking (or) decomposition.
-A crude oil distillation plant has many parts like a crude oil furnace, towers for distillation, and a heat exchanger network. There are two systems for crude oil distillations units,
-Atmospheric distillation unit
-Vacuum distillation unit
One of the important products of crude oil distillation is naphtha, raw material of petrochemical plants.
The distillation of crude oil is known as fractionation.
Hence, Option (C) is correct.
Note:
We have to know that CDU is important in refineries, and retrofitting a crude oil distillation is more common than constructing a new one. Some of the primary-end products in petroleum refining are light distillates, middle distillates, heavy distillates and others.
