A mathematical expression to predict the influence of ethanol concentration on distillation behavior of gasoline-ethanol fuel blend and impact of non -ionic surfactant on E20 fuel
Blending of primary alcohol in gasoline surges the vapour pressure significantly and exhibits azeotrope behaviour that effect severely on the atmospheric distillation yields. In this experiment, primary alcohol (Ethanol) were blended in varied volumetric proportion (5%, 10%, 15%, 20%, 25%) with hydrocracked gasoline, influence on volatility behaviour and distillation properties were investigated. Physical properties of this blends were investigated for vapour pressure (VP), VLI, DI and distillation which were selected to evaluate the influence of alcohol in azeotrope behaviour of the fuel mix reflected through pattern of distillation curve (temperature vs % recovery range). This fuel mix exhibited rise in recovery at 700C (E70), VP, VLI and area of azeotrope with increase in % of alcohol volume in gasoline blend.
