The longest hydrocarbons have very high boiling points. They leave the column as a hot liquid called bitumen. Shorter hydrocarbon molecules have weaker intermolecular forces and lower boiling points.

Imagine a humble, dark liquid pulled from deep within the Earth, mysterious, dense, and seemingly simple. Yet, in the right ...

Distillation columns are extensively deployed in the chemical process ... Examples are the separation of crude oil into components, such as gasoline, kerosene, and diesel fuel; the separation of raw ...

Many separation processes depend on chemical or thermal principles, such as solvent extraction or distillation, but in some ...

Crude oil comes into a refinery and goes into what is called a crude distillation unit. “There, there is the distillation column and products come out from the column at various levels.

Other products are e.g. lubricants and asphalt. The most important step in the refinery is distillation. Crude oil is heated and headed through a column. This process yields several petroleum products ...
