The rectifying section in a distillation column is the upper portion where the rising vapor is enriched in the more volatile component by contact with the descending liquid. This section plays a crucial role in determining the purity of the distillate as it allows for multiple stages of vapor-liquid equilibrium to enhance separation efficiency.

Rectifying Section

A distillation column is an essential piece of equipment in chemical engineering used for separating mixtures based on differences in volatilities of components in a boiling liquid mixture. It operates on the principle of repeated vaporization and condensation cycles, enhancing the purity of the separated components through multiple stages or trays within the column.

Separation efficiency is a measure of how effectively a separation process can divide components of a mixture into distinct products, maximizing the purity and yield of desired components. It is crucial in industries like chemical engineering, environmental science, and biotechnology, where precise separation processes are essential for product quality and process optimization.
