Steps Involved In Vacuum Distillation
In vacuum distillation, the process involves several key steps that are essential for the successful separation of components based on their boiling points under reduced pressure.
The first step is charging the feed mixture into the distillation flask, where the mixture is heated to reach its boiling point. As the mixture vaporizes, the components with lower boiling points rise while those with higher boiling points remain in the liquid phase.
Next, the vaporized components pass into the fractionating column, where they undergo further separation due to the differences in boiling points. The column provides a larger surface area for the vapor to condense and revaporize, aiding in the separation process. Finally, the separated components are collected in different receivers based on their boiling points, resulting in the desired purified products.
Overall, the steps involved in vacuum distillation are crucial for achieving the efficient separation of components in a mixture, making it a valuable technique in various industries such as petrochemical, pharmaceutical, and food processing.
