Answer 1

Answer:

Fractional distillation

The separation of various components of crude oil is one of the very common examples of fractional distillation in the industry. Paraffin wax, diesel, lubricating oil, gasoline, kerosene and naphtha are the substances that crude oil contains.  At this particular point, various substances start entering the vapour phase.

Distillate

Distillate is the process of separating components of a mixture based on different boiling points. Examples of uses of distillation include purification of alcohol, desalination, crude oil refining, and making liquefied gases from air. Humans have been using distillation since at least 3000 BC in the Indus valley.

Distillation

Distillation is defined as a refining process that collects the pure liquid or vapors given off by heating and then cooling a mixture. An example of distillation is how vodka is made from a grain. The distillation of water.
