Plastics: A simple introduction - Explain that Stuff

Dec 10, 2020 That happens in an oil refinery, through a process called fractional distillation. It's a more involved version of the distillation you might have used to purify water . If we heat water, it eventually turns into steam, which we can then collect, cool, and condense back to water; that's distillation, and it produces highly purified or ...

Distillation - Wikipedia

Distillation, or classical distillation, is the process of separating the components or substances from a liquid mixture by using selective boiling and condensation. Dry distillation is the heating of solid materials to produce gaseous products (which may condense into liquids or solids). Dry distillation may involve chemical changes such as destructive distillation or cracking and is …

petroleum refining, conversion of crude oil into useful products. The refining of crude petroleum owes its origin to the successful drilling of the first oil wells in Ontario, Canada, in 1858 and in Titusville, Pennsylvania, U.S., in 1859. Prior to that time, petroleum was available only in very small quantities from natural seepage of subsurface oil in various areas throughout the world.

The value of such an equilibrium fractionation factor can be calculated on the basis of spectral data of the isotopic molecular species, at least for simple molecules. The a values generally differ by just a few percent from the equal-energy value of 1.00, except for exchange reactions involving hydrogen isotopes where a values may be as large ...
