Extractive distillation is an alternative for ethanol dehydration processes that has been shown to be more effective than azeotropic distillation and, in close proximity, to be very competitive ...

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% ...

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 ...

The technology of the heat-integrated distillation column (HIDiC) has shown to be a potential energy-saving alternative for separating close-boiling mixtures. However, the economic aspects are a ...

'Pure' has a specific meaning in chemistry. A pure substance is a single element or compound not mixed with any other substance. A mixture contains two or more different substances mixed together, ...
