Modeling the partitioning of BTEX in water-reformulated gasoline systems containing ethanol

摘要

The objectives of this research were to quantify the extent of cosolvency for water-gasoline mixtures containing ethanol and to identify appropriate modeling tools for predicting the equilib- rium partitioning of BTEX compounds and ethanol between an ethanol-bearing gasoline and water. Batch-equilibrium experiments were performed to measure ethanol and BTEX partitioning between a gasoline and aqueous phase. The experiments incorporated simple binary and multi- component organic mixtures comprised of as many eight compounds as well as highly complex commercial gasolines where the composition of the organic phase was not completely defined.
