Aden Refinery company with its office located in little Aden At Al Buriqah district, Aden governorate, The republic of Yemen was basically owned by the British oil company (BP) who established and constructed it from 1952 to 1954 as the production had commenced on July 1954. The production capacity of this refinery initially is 120,000 Barrel per day (Kuwaiti Crude) then it expanded in the sixties (1960’S) to reach a production of 150,000 Barrel per day (Kuwaiti Crude) and remained on that level of production.
In May 1977 the ownership of this refinery transferred to the Yemen government and thus its name changed to Aden Refinery Company, and on 1979 the same were occurred with the British oil (Aden Oil) Limited, located at Steamer point, Aden, which is specialized in supplying fuel to vessels and it was merged to Aden Refinery Company under new administration having the name of Aden Administration for shipchandelling.
This refinery is one of those which uses Hydrogen to process its products (Hydro Skimming Refinery) and designed to process high Sulfur crude (Kuwaiti crude / Qatar Crude), during its refining episode it refines crude from various resources from the Middle east, north Africa, Russia and Iran up to the mid nineties (1990’S) when Mareb Crude had replaced them and became the main crude available for refining.
Geographically Aden Refinery Company is divided to four locations (Areas) that consist of the following:-
A- Refinery Area:

A-2: Reservoirs Field:
It contains one hundred and one (101) metal reservoirs of different sizes, kinds for crude oil and its derivatives (for both areas of Refinery and Coast) it provides a reserving capacity for Aden Refinery Company estimated with about two hundred million (200) imperial Gallon.
Then after between 1992 and 2002 the field is developed by adding thirty (30) new reservoirs and repairing many of the existing once in order to increase the reserving capacity of the company and to compensate for out of order reservoirs.
Pumping stations (Beyot) and joining pipe group.
Aden’s Oil Pipe Line (with a length of 35 kilometer approximately from the Refinery to Aden Administration for shipchandelling).
A-3: Power station: furnishes the Refinery with the following:
1- Generating electricity: three electrical generators works on steam turbines each of a power of 7.5 megawatt.
2- Steam production: Four boilers each of a power of 160,000 steam pound per hour, with a pressure of 600 pound per square inch and a temperature of 750◦F.
3- Pumping cooling water to refinery: (Sea water): 3,300,000 Gallon per hour approximately.
4- Producing distilled water: 7600 Gallon per hour approximately.
5- Producing Oxygen.
6- Producing air: Operating precise equipments at the Refinery for other type of usage.
A-4: Different Systems and service centers:
• Treating service systems (Flame, Quick discharging and separators etc…)
• Safety and fire fighting service system.
• Maintenance workshops.
• Transportation services, vehicles and heavy equipments station.
• Crude materials Laboratory.
• Training center.
• Materials and spare parts stores.
• Administration Buildings.
B- Coast Area:
B-1: Oil port:
◄ Four berths for crude oil and its derivatives repaired and modernized on 1987 / 1989. Three of these can receive vessels with a load of 80,000 tons the fourth one can receive vessels with a load of 110,000 ton.
◄ New berth for Asphalt and liquid gas (Constructed on 1989) can receive vessels with a load of 22000 ton.
◄ Sea anchor for each of: Spirals, Boats and skiffs and materials all of them were maintained in 1987 / 1989.
◄ Three Tankers: Qana (3000 ton), Masealah (13800 ton) and Bab al Mandab (6000 ton).
B-2: Reservoirs Field:
◄ Metal reservoirs for crude and its derivatives (See Reservoirs Field in Refinery area, page 6)
◄ Spherical shape reservoirs for liquid gas each of a capacity of 250 ton, an area of 450 m� (one of them is out of order for some years).
◄ Three new Spherical shape reservoirs for liquid gas each of a capacity of 875 ton, an area of 1700 m� (constructed on 1985 – 1987).
◄ Ten new cylindrical shape reservoirs for liquid gas each of an area of 250 m� (Constructed on 2000-20010
◄ Pumping stations and joining pipe grid.
B-3: Different Systems and service centers:
– Treatment systems and service centers (Al Mafrkat, Al Wahl etc…).
– Safety and fire fighting service system.
– Marine stores.
– Administration buildings.
C- Aden administration for ship chandelling:
Fixed sea berth.
Floating sea berth.
D- General Services:
Aden Refinery Hospital (100 beds).
Aden Refinery club.
1-4 Short historical resume about developing planes and modernization of Aden Refinery Company:-
Since the year of 1983 Aden Refinery Company sets planes, developing programs, modernizing the refinery and searching for means and ways to attain it therefore several technical studies were prepared to recognize and specify the required developing and modernizing quality and quantity performed by companies and recognized consulting institutions, out of these studies are the following:
U Bank Survey (EWBank) for renewing power station on 1985.
Star energy / UOP survey on developing and modernizing the Refinery on 1988.
Japanese consulting institute (JCI) on developing and modernizing the Refinery on 1989.
AMEC process energy ltd survey on 1995 in which it specified the required developing and modernizing quality and quantity therefore these survey documents on 1996 are converted to tender deeds for Rehabilitation and modernization project of Aden Refinery, and put for international tender invitation in the same year.
Kvaerner John Brown Survey which is an amendment for the prepared tender documents by AMEC for Rehabilitation and modernization of Aden Refinery to anew tender documents of Modernization project for Aden Refinery in order to get a large number of participating companies.
But due various reasons Aden Refinery Company could not execute except the following large projects only:-
1. Constructing units of vacuum distillation, asphalt, extracting ethane gas, filling asphalt barrels, three Spherical shape reservoirs for liquid gas and six metal reservoirs for asphalt (Period: 1985 – 1987).
2. deepening and repairing and modernizing crude oil and derivatives berth with its premises, and to build new berth for asphalt and liquid gas (Period: 1987 – 1989).
3. Modernization of reservoirs field by adding new reservoirs for crude oil, derivatives, Asphalt and liquid gas and to repair the old reservoirs (Period: 1992 – 2002).
4. Purchasing of three tankers:
Al Masealah: 1993.
Bab al Mandab: 2001.
Recently the plane of Aden Refinery Company for large project is restricted to the following two projects:-
1. Constructing crushing compound with catalysis for atmospheric distillation residual so that the capacity of crushing unit would be: 25000/30000 Barrel per day.
2. Rehabilitation / renewal and modernization of power station.
