2016-5-11 · Fractional distillation. Molecules which strongly interact or bond with each other through a variety of intermolecular forces cannot move easily or rapidly and therefore, do not achieve the kinetic energy necessary to escape the liquid state. Therefore, molecules with strong intermolecular forces will have higher boiling points.

Crude Oil & Fractional Distillation (4.2.1) | Edexcel

Properties of the main fractions of crude oil. Viscosity: This refers to the ease of flow of a liquid.High viscosity liquids are thick and flow less easily. If the nuer of carbon atoms increases, the attraction between the hydrocarbon molecules also increases which results in the liquid becoming more viscous with the increasing length of the hydrocarbon chain.

Principle and Procedure of Molecular Distillation

2021-5-13 · Working of Molecular Distillation: The vessel walls are heated suitably by a heating jacket. The feed flows down the walls and is spread to a film by the polytetrafluoroethylene (PTFE) wipers which move about 3 m/s giving a film velocity of about 5 ms. Due to heat liquid film evaporates and vapors hit the condenser.
