What is partial vaporization?

Answer 1

By adding heat to the liquid feed mixture, a part of the components will evaporate, thus the partial vaporization. The vapors, with the lower density, will go up the fraction column and the liquid remained will go on the bottom of the column (higher density).

Answer 2

Partial vaporization refers to the process in which only a portion of a liquid is converted into vapor. This can occur when heating a liquid to its boiling point, where only some of the liquid evaporates while the rest remains in its liquid form. This phenomenon is commonly observed in distillation processes.
