Libyan refining sector needs upgrading after years of sanctions.
Libyans refining sector was hard hit by UN sanction which banned
Libya from importing refinery equipment.
Libya is seeking a comprehensive upgrade to its entire refining system,
with a particular aim of increasing output of gasoline and other light
products and enabling them to conform with new global fuel
specifications.

NOC Strategies to meet the Latest Clean Fuels Specifications
With the current trends for tighter specification for both gasoline and
diesel, National Oil Corporation (NOC) has adopted a long - term strategy
for meeting these new goals. The steps involved in the NOC strategy
development are:
1. Producing clean fuels at the lowest possible cost, at the same
time giving the best return on investment.
2. Developing a wide range of ideas for possible solutions to meet
the objectives.
3. Developing a selected options for further consideration.
4. Costing the options and assessing the economic viability.
5. Recommending a strategy and an investment roadmap.

Introduction
Azzawiya Oil Refinery is the first Refinery to be built by National Oil
Corporation in Libya. In 1974, the refinery began production with a
nameplate capacity of 60,000 b/d and in 1977, capacity doubled to
120,000 b/d. The two units with an identical capacity of 60,000 b/d
process Al Shararah (43 API) and Hamada ( 38 API ) crude oil with a
ratio of 90 % and 10 % , respectively.
-
Azzawiya Principal Activities
1. Refining of Crude Oil to produce LPG, St. Run Naphtha,
Gasoline, Kerosene, Gas Oil and Fuel Oil.
2. Processing of Reduced Crude Oil to produce Asphalt.
3. Lubricating Oil Blending Plant (including Filling and
Canning) to produce different grades of Lubricating Oils.

Azzawiya Refinery Upgrading Objectives
INDUSTRIAL DEPT
-
Future Upgrading Project
Future upgrading project target the enhancement of Azzawiya Refinery
economical resources through increasing the revenue against refining crude oil
when production output is increased so that produced amounts can cope with
consumed amounts; eventually, this helps overcome the shortage of gasoline now
encountered.
Furthermore, this aims to the improvement of oil products, enabling them to
conform with global specifications.
It also helps in the treatment of gas wastes and oil residue in order to protect the
environment and the surroundings.
Within these project, the Harbor in intended to be expanded to meet
importation and exportation requirements of the oil and oil products.

Azzawiya Refinery Upgrading Project
Naphtha Conversion Process units
This phase targets:
1. Upgrading the refining capacity and the multiplication
of gasoline production.
2. Updating the control and measurement systems.
3. Improving diesel specifications and treating oil
residue so as to protect the environment.
4. Contribution to economical growth.
Residue Conversion Process units
This phase is still under consideration. It targets the cracking and
transforming of heavy fuel oil into highly economical white products,
and also increasing the produced gasoline and optimizing the
economics of the Refinery in a way that achieves good profitability.

Conclusions:
Producing Clean fuel is clearly a challenge in term of environmental
impact and capital investment. The need for converting heavy fuel oil to
valuable lighter products and for producing low sulfur gasoline and diesel
fuel will continue to encourage refiners to evaluate proven hydrotreatment
and residue conversion process options.
Fluid Catalytic Cracking and Hydrotreatment units are powerful tools that
refiners can use to meet future market demands and product specifications.
These tools offer solutions to address major challenges such as the
decreasing heavy fuel demand, the need for low sulfur diesel fuel, reduced
sulfur emission, reduced sulfur content in gasoline, and the increasing of
gasoline and diesel production.
