Background

Distillation is a thermodynamic separation process that utilizes the difference in boiling points of components in a mixed liquid or liquid-solid system to vaporize lower boiling components and recondense to separate the entire component, a unit operation that combines the two unit operations of evaporation and condensation. Compared with other separation means, such as extraction, filtration crystallization and the like, the method has the advantage that other solvents except system components are not required, so that new impurities are not introduced.
