Industry separates crude oil, natural gas and chemical mixtures into pure products by means of fractionating distillation columns. This process is energy-intensive, but a new type of column structure ...

Simple distillation close simple distillationSeparation method used to separate a solvent from a solution. is a method for separating the solvent from a solution. For example, water can be separated ...

In producing hydrocarbons for the chemical industry, refiners must first crack oil at high temperatures and then cool the mixture to liquefy the gases for separation. This energy-intensive chilling ...

Listen to the full series on BBC Sounds. Fractional distillation works because the different liquids have different boiling points. When the mixture is heated: vapours rise through a column which is ...

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% ...

CORRECTION: This story was updated on Dec. 16, 2015, to correct the description of distillation and to clarify the separation difficulty posed by azeotropes. A new method for heating liquid mixtures ...

A solid sorbent that selectively binds hydrocarbons may help the petrochemical industry reduce costs and energy consumption by increasing the efficiency of—or eliminating—energy-intensive separations ...

For centuries, distillation has been used to separate the components of liquid solutions through extremely selective heating and cooling. Numerous instruments are used to control the differing ...

Distillation remains a backbone technology in the chemical process industry despite its historically high energy consumption. In recent years, research has focused on improving the thermal efficiency ...

A recent report in the journal Science Advances from researchers at the University of Kansas shows a new eco-friendly method for separating the chemicals found in common refrigerants for easier ...
