Vacuum distillation - Wikipedia

The vacuum distillation column internals must provide good vapor–liquid contacting while, at the same time, maintaining a very low-pressure increase from the top of the column top to the bottom. Therefore, the vacuum column uses distillation trays only where withdrawing products from the side of the column (referred to as side draws ).

distillation | Definition, Process, & Methods | Britannica

May 12, 2020 · Distillation, the process involving the conversion of a liquid into vapor that is subsequently condensed back to liquid form. It is used to separate liquids from nonvolatile solids or in the separation of two or more liquids having different boiling points. Learn more about distillation .

Types of Distillation | Sciencing

Distillation is a procedure that separates a mixture of liquids with different boiling points. Distillation is a useful technique in chemistry labs, where chemists use it to purify a compound, and also in industry, especially in the petrochemical and refining industry .

Vacuum Distillation - ValvTechnologies

Vacuum Distillation – Application Guide Vacuum distillation works on the principle that boiling occurs when the vapor pressure of a liquid exceeds the ambient pressure. In vacuum distillation, the pressure above the reduced crude to be distilled is reduced to less than its vapor pressure, via vacuum and stripping steam, resulting on .

Membrane distillation - Wikipedia

Membrane distillation (MD) is a thermally driven separation process in which separation is driven by phase change.A hydrophobic membrane presents a barrier for the liquid phase, allowing the vapour phase (e.g. water vapour) to pass through the membrane's .

Vapor Compression Distillation - WFI From Vapor .

Vapor compression distillation (VC) is a process used to produce Water for Injection (WFI) on the principle of distillation, where the water is distilled with phase change and entrainment separation. In the VC process, the vapor produced by evaporating the water is compressed to increase the saturation pressure and temperature.

Difference Between Atmospheric Distillation and Vacuum .

Apr 14, 2018 · What is Vacuum Distillation? Vacuum distillation is a technique used to separate components in a mixture at a reduced pressure. This process is used when the components in the mixture have boiling points which are difficult to be achieved or if higher temperature cause the compounds to be decomposed instead of vaporizing.
