2. Gas blending - Wikipedia

   en.wikipedia.org/wiki/Gas_blending

   Gas blending is the process of mixing gases for a specific purpose where the composition of the resulting mixture is defined, and therefore, controlled. A wide range of applications include scientific and industrial processes, food production and storage and breathing gases.

3. Common ethanol fuel mixtures - Wikipedia

   en.wikipedia.org/wiki/Common_ethanol_fuel_mixtures

   E85, a mixture of 85% ethanol and ~15% gasoline, is generally the highest ethanol fuel mixture found in the United States and several European countries, particularly in Sweden, as this blend is the standard fuel for flexible-fuel vehicles. This mixture has an octane rating of 108, however, the Ethanol molecule also carries with it an oxygen ...

4. Gasoline - Wikipedia

   en.wikipedia.org/wiki/Gasoline

   The bulk of a typical gasoline consists of a homogeneous mixture of hydrocarbons with between 4 and 12 carbon atoms per molecule (commonly referred to as C4–C12). [7] It is a mixture of paraffins , olefins , napthenes (cycloalkanes), and aromatics.

5. Viscosity models for mixtures - Wikipedia

   en.wikipedia.org/wiki/Viscosity_models_for_mixtures

   In a fluid mixture like a petroleum gas or oil there are lots of molecule types, and within this mixture there are families of molecule types (i.e. groups of fluid components). The simplest group is the n-alkanes which are long chains of CH 2-elements. The more CH 2-elements, or carbon atoms, the longer molecule. Critical viscosity and critical ...

6. Mixing (process engineering) - Wikipedia

   en.wikipedia.org/wiki/Mixing_(process_engineering)

   Mixing of liquids occurs frequently in process engineering. The nature of liquids to blend determines the equipment used. Single-phase blending tends to involve low-shear, high-flow mixers to cause liquid engulfment, while multi-phase mixing generally requires the use of high-shear, low-flow mixers to create droplets of one liquid in laminar, turbulent or transitional flow regimes, depending ...

   One result of those slack prices is that U.S. average pump prices for gasoline fell to $3.03 a gallon this week, the lowest since May, 2021 and well down from their record peak of $5.02 from June ...
