Gasoline Blending By The Interaction Coefficient Method2

In a given refinery, where the maximum number of gasoline blend components and their properties are known, it is possible to develop an accurate blending spreadsheet program, using the individual blendstock properties and the binary blend interaction coefficients. The only additional laboratory work required is the determination of the properties: RON, MON, and ASTM distillation of all possible binary blends for a given number of blend components.

Interaction coefficients are determined for all binary blends and used in the model to accurately predict the properties of any gasoline blend of these components.
