In this video, Fran Scott explains fractional distillation - the separation of crude oil into fractions. Crude oil is a finite resource; petrol and other fuels are produced from it using fractional ...

This process is energy-intensive, but a new type of column structure promises energy savings of as much as 20 - 40 percent. The petroleum industry relies on fractional distillation of raw materials to ...

During the fractional distillation of crude oil: ...

Purifying mixtures without using heat would lower global energy use, emissions and pollution — and open up new routes to resources, say David S. Sholl and Ryan P. Lively. You have full access to this ...

Distillation columns are extensively deployed in the chemical process industries when there is a need for separation of components that have different boiling points. Typically, a mixture of ...

Introduction Do you like cooking? If you have helped in the kitchen at home or watched someone else cook, you have probably seen lots of liquids—such as water, milk and soup—heated. Did you notice ...

Thermally-based industrial chemical separation processes such as distillation now account for 10 to 15 percent of the world's annual energy use. Slaking the global thirst for energy could therefore ...

Most industrial chemists spend their days separating the components of large quantities of chemical mixtures into pure or purer forms. The processes involved, such as distillation, account for 10–15% ...

The authors argue that the cost of generating nitrogen via an in-house gas generator is considerably lower than the cost of using fractional distillation to generate liquid nitrogen. Nitrogen gas is ...
