| Abu Dhabi Refinery |
| |
| Following the discovery
of oil in Abu Dhabi in 1958, and the first export
shipments of Crude in 1962, plans were drawn up
for a grass root Refinery with a capacity of 15,000
barrels per stream day (BPSD) to meet a growing
local need for petroleum products. Construction
work on the project began in 1973 and the Refinery,
costing an initial $45 million, was inaugurated
in April 1976. |
| |
So rapid was
the growth in demand for oil products, however,
that work began almost immediately on installing
a new Refinery to process a further 60,000
BPSD and this was commissioned in 1983.
Requirements continued to grow in the fast-developing
Emirate, and ADNOC decided to expand capacity
yet again, with environmental considerations
in mind, to include additional units for Gas
Oil Desulphurization and Sulphur recovery.
The expanded Refinery started up in December
1992 with a rated capacity of 85,000 BPSD. |
 |
|
| |
A Salt and Chlorine
Plant, commissioned at Umm Al Nar in 1981, was merged
in 1990 with the Refinery to form the Abu Dhabi
Refinery and Chlorine Division.
Subsequently it was permanently shutdown on 30th
November, 2001. Two power plants, owned and operated
by Umm Al Nar Power Company, and a Lube oil blending/filling
plant, owned and operated by ADNOC Distribution,
are located adjacent to the Refinery. |

| Refinery Installations |
| The Refinery
is a Hydro Skimming Complex designed to process
Bab Crude as well as a mixture of Asab-Sahil,
Shah and Thammama Condensate. |
| |
| Finished products
from the Refinery are as follows : |
| |
 |
Liquefied
Petroleum Gases |
|
Naphtha |
|
Unleaded
Gasoline |
|
Aviation
Turbine Kerosene |
|
Domestic

| Refinery units
include: |
| |
Crude
Distillation Unit (85,000 BPSD)
As a first step, prior to the actual distillation
process, Crude Oil is passed through a Desalter
Unit to remove the undesirable salts, water
and sludge which are generally associated
with any type of Crude. After final heating
in a furnace, the Crude is then fractionated
in the Atmospheric Distillation Column into
the basic raw petroleum fractions of Naphtha,
kerosene, Gas Oil and Straight Run Residue.
Naphtha Hydrodesulphuriser
Unit (22,500 BPSD)
The Naphtha Hydrodesulphuriser sweetens the
Straight Run Naphtha from Crude Unit. Three
products are produced in this unit namely,
Heavy Naphtha, Light Naphtha and Sour Liquefied
Petroleum Gases.
Kerosene
Merox Unit (21,250 BPSD)
The unit converts Mercaptans in straight run
kerosene into disulphide to meet the final
product quality for aviation kerosene.
Catalytic Reformer
Unit (14,000 BPSD)
The Reformer processes the Heavy Naphtha cut
to improve its anti-knock properties prior
to using it as a Gasoline blending component.
The Unit is a continuous regeneration type
and does not need to be shut down periodically
for regeneration of catalyst.
Gas
Oil Hydrodesulphuriser Unit (22,500 BPSD)
The Gas Oil Hydrodesulphuriser Unit reduces
Gas Oil sulphur content to 0.15 wt% to improve
product quality.
LPG
Treating and Recovery Unit (3,480 BPSD)
Raw LPG from Naphtha Hydrodesulphuriser and
Catalytic Reformer Unit are processed in this
unit. Butane produced is used as a blending
component in Gasoline and also blended with
Propane to form LPG for domestic use.
Naphtha Stabilizer
Unit (3,630 BPSD)
Excess Naphtha from Crude Unit is stabilized
prior to export to Ruwais Refinery.
Gas Sweetening Unit
(40 tons/day H2S Removal)
Sour Gases produced in the Refinery facilities
are sweetened using amine solution to remove
hydrogen sulphide to minimize sulphur oxide
emissions.
Sulphur
Recovery Unit (40 tons/day)
The acid gases produced from Gas Sweetening
Unit are converted to liquid Sulphur, which
is then transported to Ruwais Sulphur Handling
Terminal via Road tankers.
Jarn
Yaphour Crude Oil Stabilization Plant (10,000
BPSD)
The Oil/Gas Separation Plant is designed to
stabilize Crude from Jarn Yaphour Wells, located
some 30 kilometers from Umm Al Nar. The separated
gas is further treated to remove hydrogen
sulphide, water and hydrocarbon condensate
before it is injected into GASCO’s Main Gas
Network. The Stabilized Crude is sent to the
Refinery Crude Distillation Unit for further
separation into petroleum fractions.
Additional Effluent Water Treatment facilities
were installed to adhere to rigid oil in water
specification of 10 ppm maximum. |
| |
|
| Utilities |
| The Refinery
receives power and fresh water supplies from the
Adjacent Plant of the Abu Dhabi Water and Electricity
Authority. Steam, Air, Nitrogen and Sea Water for
cooling are all provided by the Refinery's own facilities.
The Refinery’s Fuel Gas supply is supplemented by
Natural Gas from the GASCO Main Network. |
| |
| Off-sites |
| Storage Capacity of Abu Dhabi Refinery Tank Farm is 500,000 cubic meters, which includes facilities for Crude Oil, Intermediate Streams, Semi-Finished Products, Finished Products and Utility Fuel Oil. Most of the Refined Products from Abu Dhabi Refinery are sold in the ever expanding domestic market, while the Residue and Naphtha are shipped to Ruwais Refinery. |
|
| |
| Marine Terminal |
| The Refinery is served
by a two-Berth Marine Terminal on the North Shore
of the Island for loading and unloading of tankers.
Maximum Draft is 9.5 meters; maximum Cargo is 30,000
tons. |
| |
| ADR Technology |
In 1994, Abu Dhabi
Refinery completed the process of installing a fully
integrated state-of-the-art Computerized System
designed to Modernize Operations. The first level
was achieved in January 1993 with the commissioning
of a new Consolidated Control Room under the overall
Refinery expansion project.
The Refinery is equipped with a Distributed Control
System (DCS), which allowed for the introduction
of an Advanced Process Control system as part of
the Process Automation and Computerization project
(PACS).
PACS has been designed to provide accurate and up-to-the-minute
information on every aspect of the Operations in
Support of Operational and Management Activities. |
| |
| The second level
of the project includes the implementation
of Advanced Process Control (APC) strategies
and off-site Automation and Computerization,
while the third level involved the implementation
of a plant-wide Data Base and Communications
Network, leading to the use of a Computerized
Decision Support System in laboratory management,
Planning, Scheduling, Mass Balancing, Oil
Accounting and Performance Monitoring. |
