Integration of Petrochemical and Refinery Plants: An Approach to Optimal Utilization of Hydrocarbon Resources

From a global point of view, petrochemical industries were always competitive. Specially, because of fluctuations in productsʹ price and high price of feedstocks, earning money in petrochemicals is always a challenge. In the case that cheap feedstocks are not available, the best method of profitability is integrational optimization in petrochemical complexes and in their adjacent refineries. This fact is valid for installed plants and plants under construction. Petrochemcial-refinery integration is an important factor in reducing costs and increasing efficiencies. Moreover, it guarantees the supply of feedstock for petrochemical industries. Integrated schemes benefits from the economy of scale. On the other hand, an integrated complex can produce more diverse products. "Benchmarking " is the methodology used in this study. Petrochemical-refinery integration avoids selling crude oil, optimizes products, economizes costs and increases benefits. Nowadays, there is an integration approach in various commercial processes of well-known licencing companies.
