Reformate-enriched gasoline-ethanol blends: Volatility criteria and azeotrope formation
Egyptian Journal of Petroleum, 2019 Four hydrocarbon-base gasolines (BG) were formulated from the local refinery streams; isomerate, reformate, and light naphtha. The formulations were enriched in reformate. Each of these BG formulations was blended with 10 vol% of anhydrous ethanol.

Residue curve maps of 4-component systems. Poincare index determination for 4-component azeotrope
Тонкие химические технологии, 2011 A method of Poincare index determination for a singular point corresponding to a 4-component azeotrope is proposed. The method is based on the equation of azeotropic relationship.

New extractive configuration separating azeotropic mixture in semi-batch way [PDF]
, 2006 A new variant of batch extractive distillation, the so-called inverse-fed batch extractive distillation is presented. The total amount of the entrainer is pre-loaded to the boiler, and the mixture charge to be separated is continuously fed to the column ...

Using Ionic Liquids To Break the Ethanol–Ethyl Acetate Azeotrope [PDF]
, 2015 Systems that form azeotropes or have relative volatilities close to 1.0 represent very little energy and capital intensive separations. Ionic liquids (ILs) can serve as nonvolatile entrainers to break azeotropes and enable a more energy efficient and ...
