Optimal blending study for the commercial gasoline

Commercial ecological gasoline is being obtained by blending multiple components. Increasing a refinery's economic performance depends, among other things, on obtaining optimum blending recipes for the available components. To determine the optimum blending recipe, knowing the mathematical blending model for blending properties estimation and a linear optimization algorithm are necessary. As a blending properties estimation model, the authors used a mathematical model which can be found in the literature, validated through own laboratory experiments. Based on the Simplex algorithm developed by Jean-Pierre Moreau, the authors elaborated a software program, program that was used to study different blending recipes. The studied recipes varied from recipes that took into consideration one restrictive blending property, to recipes that took into consideration two restrictive properties and recipes that took into account one restrictive property, but a fixed proportion of bioethanol in the final blending.
