What determines the initial boiling point of oils?

Thread Content

The dry point of the distillation range of petroleum products is determined by temperature, which is easy to understand; it relates to the heaviness or lightness of the components. But what about the initial boiling point?

It is also determined by temperature. It is also related to the weight of the components.

The lowest temperature at which liquid droplets begin to distill during the distillation of oil products

It’s the same; the boiling range is determined by the initial boiling point, which is set by the lightest component in the mixture, while the dry point is determined by the heaviest component. There’s another thing you misunderstand: it’s not the temperature that determines the boiling range, but rather the components. Temperature is just a point at which this component vaporizes.

Oh, doesn’t temperature control the components during distillation?

Does this imply a relative meaning? It refers to the first drop of this type of oil; I think heavy oil can also be vaporized, right?
