20 Questions
What is the function of the crude distillation unit (CDU) in the petroleum refinery?
It is at the front-end of the refinery and is responsible for crude distillation.
What are some of the products obtained from the petroleum refinery?
Petroleum naphtha, gasoline, kerosene, diesel fuel, asphalt base, and fuel oil
How are petrochemicals feedstock like ethylene and propylene produced in the petroleum refinery?
Directly by cracking crude oil without the need of using refined products of crude oil such as naphtha
What are some of the characteristics of oil refineries in terms of their size and infrastructure?
Typically large, sprawling industrial complexes with extensive piping running throughout
Where is the oil depot usually located in relation to an oil refinery?
At or near the refinery for the storage of incoming crude oil feedstock and bulk liquid products
What are the typical products from the Crude Distillation Unit (CDU)?
Gases, Light straight run naphtha, Heavy gasoline, Kerosene, Middle distillates, Heavy distillates, Crude column bottoms
At what percentage of the design feed rate should the CDU run satisfactorily?
About 60%
What is the temperature range to which the crude oil can reach during the initial heating process in the CDU?
120-150 °C (248-302 °F)
How high is the main column typically in the atmospheric distillation process?
50 m (164 ft)
What is the purpose of injecting steam into the column at the bottom of the stripping section?
(1) To strip the atmospheric residue of any light hydrocarbon and (2) to lower the partial pressure of the hydrocarbon vapors in the flash zone.
What is the main function of an oil refinery?
Refining crude oil into useful products
Where is the crude distillation unit (CDU) located within the refinery?
At the front-end of the refinery
What are some of the major products obtained from crude distillation in a refinery?
Gasoline and diesel fuel
What type of plant usually processes the crude oil feedstock before it reaches the refinery?
Oil production plant
In what ways can oil refineries be thought of?
As industrial complexes with extensive piping
What is the typical range of the capacity of a Crude Distillation Unit (CDU)?
10,000 - 400,000 BPSD (1,400 - 56,000 tpd)
What temperature range is required to boost the temperature of the crude oil in the atmospheric distillation process?
300 - 380 °C (572 - 716 °F)
At what percentage of the design feed rate should the Crude Distillation Unit (CDU) run satisfactorily?
60%
What are the typical products obtained from the Crude Distillation Unit (CDU)?
Heavy Gas Oil (HGO), Light Naphtha, and Jet Fuel
What is the purpose of injecting steam into the column at the bottom of the stripping section in the atmospheric distillation process?
To strip the atmospheric residue of any light hydrocarbon and lower the partial pressure of the hydrocarbon vapors in the flash zone
