Distillation plays a role in creating all of these everyday products:
Whisky
In production of spirits (such as whisky), distillation is used to increase alcohol content of liquid
Biofuels
Biofuel production, such as ethanol, can be purified from water by using distllation due to their different boiling points
Crude oil
Extracted from oil wells, crude oil needs elaborate processing via distillation for it to become fossil fuels that we can use.
Refining chemicals
Production of most household chemicals employ distillation to refine mixtures.
Juice
Frozen and/or concentrated juices are often produced by using low temperature distillation to remove excess water content.
Perfume
Distillation is used to extract fragrant compounds from natural sources, which are then used for manufacturing perfume.
