Abstract
To integrate or not to integrate petrochemicals – that is the question posed by this paper for Saudi Arabian oil refineries. The viability of combining domestic oil refining and petrochemical activities is investigated using an energy system model for Saudi Arabia. Two scenarios are examined: one allows intermediate naphtha streams to flow freely from refineries to petrochemical equipment, while the other prevents petrochemical units from using intermediate naphtha. The modeling analysis reveals present cost savings of $10 billion from 2023 to 2060 due to integration. Since two Saudi refineries are already equipped with petrochemical processes, the lower cost indicates that the integration of the two activities has been beneficial for both industries.
