Muller, A

The solution of a linear equation system gives individualized octane deviations from the ideal blend values. The method needs little data, produces simpler correlations, and is more accurate than others because it is highly adaptable. The deviations calculated by this method are characteristic of each gasoline component and grade. The values are derived directly from original refinery data and therefore reflect refinery-specific situations. By using these values in an LP-optimized blending model, it is possible to allocate the available components into the different gasoline grades while maximizing the output of premium gasoline. This paper reports that a computer-based octane improvement system is especially beneficial to refiners who have already squeezed the relevant process units to their limits to improve octane quality.
