Challenges Facing Libyan Oil Refineries 1- Simple Configuration 2- Limited Capacity 3- Products Specification
Why do we need to upgrade our refineries? Market Factors. Increase in the production of transportation fuels. Limited demand on Residue with high sulfur. Tighter bunker fuel regulations Economic Incentives. Low price of fuel oil. Increase yields of high value products Environmental. Products Specification. Refinery Emissions
What will Happened to Small Refineries? Because of their small size the costs on per liter production would be higher. Therefore the existing small refineries in the country maybe upgraded with limited capital investment in order to satisfy the local demand for the area.
Bottom of the Barrel Processing One of the basic problems that refinery face is how to select from among the available bottom of the barrel conversion processes the best residual processing route to meet the needs of refining objectives. Such a decision can be made only after a detailed analysis of the various alternatives. The bottom of the barrel processes can be classified into five groups, as follows: 1. Separation processes - Vacuum Distillation (VD) - Solvent Deasphalting (SDA) 2. Carbon Rejection Processes: Thermal Processing - Visbreaking -Delayed Coking -Combination Visbreaking and thermal Cracking 3. Catalytic Conversion: Residue Catalytic Cracking (RFCC) 4. Hydrogen Addition Processes: Residue Hydrocracking
In reality most crude oil process combine carbon rejection and hydrogen addition -Coking followed by hydrotreatment and/or hydrocracking - Residue HT then coking -Residue HT then RFCC -Solvent deasphating then DAO Processing (FCC, Hydrocracking). Residual Conversion Routes should be specially tailored for each refinery depending on considerations including: - Properties of the crude oil to be processed - Marketing requirements - Economics, including operating costs - Environmental control requirements

Disadvantages of the Existing Petrochemical Plants Libyan Petrochemical industries are limited in - Capacity, - Conversion units
Obstacles Faced the Execution of the Past Development Plans Refining and petrochemical industry suffered from lack of development. several projects have failed to get off the ground due to the following reasons: 1- Political situation 2-Financial Constraints 3-slump in the global petrochemical business in early 1990s
New Strategic Plan for Development and Upgrading the Existing Refineries and Petrochemical Plants Recently, MOG, NOC have established a technical committee to prepare a general strategic plan for the development of refineries, gas and petrochemical sectors.
Objectives: The main objectives of the strategic plan are: Enhance and develop the downstream sector (refineries, petrochemical) through upgrading the existing refineries and petrochemical plants and/or building new refineries and petrochemical plants with economic capacity. consider the possibility of integration between refineries and petrochemical industries and, Fulfill the following:
- Achieving maximum refining and petrochemical industries margins - securing attained supply of oil products to the local market and export the rest to the international markets - Meeting the international market specifications and environmental regulations. - Developing the human resources skills, and narrowing the tolerance with respect to health, safety and environmental compliance. - Improving cost and operational efficiencies. - Creating investment opportunity in the country. - Creating job opportunities for Libyans. - Facilitating the country s industrialization process.
Conclusions 1- The configuration of Libyan refineries are simple and the capacities are limited. As a result of this the processing cost per barrel is higher which affects negatively on the margin of the refineries. In addition, the local demand from fuels can not be met. Also Libyan specification particularly of transportation fuels are away from international specifications. Therefore expansion and upgrading of the existing refineries are necessary. 2- The petrochemical plants in Libya are limited in capacity and producing only primary petrochemical products. So, the expansion of this industry is important. 3- Recently, MOG, NOC has established a technical committee to prepare a general strategic plan for the development of refineries, and petrochemical sectors.
