Compania Espanola de Petroleos (CEPSA) embarked on an overall refinery automation program, with state-of-the-art gasoline blending being one of the highest priorities. The result of this effort is a sophisticated computerized gasoline blending system using offline LPs for initial optimal recipe calculation, an online LP for real-time blend recipe reformulation using online analyzers for blending model adjustment, complete automation of blending sequence startup and shutdown, generation of end of blend quality performance reports, and real-time integration between lab, tank gauging, plant information, and blending systems. The entry of Spain in the EEC brought with it the need to quickly adapt to the requirements of an openly competitive marketplace emphasizing no lead, oxygenated, high performance gasolines and ISO 9000 quality standards. The blending system allowed CEPSA to produce lowest cost, minimum giveaway gasolines, while having the flexibility to produce a wide variety of modern gasolines serving the Western European market. The paper describes the blender architecture, optimizer linear programming, man machine interface, and results from the blending system.
