Comparative study of vacuum and fractional distillation ...

Distillation, unlike a chemical extraction separation, is a physical separation process of chemical components based on the relative volatility of chemicals at various temperatures [15]. Many distillation techniques were applied to separate and improve the bio-oil produced from pyrolysis: direct, fractional, steam, vacuum, and molecular.

What is Fractional Distillation?

Fractional distillation is the separation of various components from a liquid homogeneous mixture. Each component typically has a different boiling point and vapour pressure than the rest, so fractional distillation can be achieved by applying a temperature gradient. The various components are condensed at different stages or levels of the ...

Distillation - University of Massachusetts Amherst

purity. Each vaporization-condensation step is known as a “simple distillation”. Thus, for this mixture, three simple distillations have produced the desired purification. Fractional Distillation. Unfortunately, each time a distillation is run, material is lost. Some evaporates into the air and some is left behind, stuck to the apparatus.

Fractional Distillation Of Petroleum - Master Chemistry

Schematic diagram of fractional distillation of petroleum. As we move from top to bottom the hydrocarbons with higher molecular mass and boiling points are separated. Their appearance is also sticky and waxy. When we move from bottom to top in fractionating column hydrocarbons with lower molecular mass and boiling points are separated.
