Q1: In stripping section of continuous distillation column, the

ANS:B - liquid is enriched with high boiler.

In the stripping section of a continuous distillation column:

• The liquid is stripped of high boilers.

Stripping refers to the process of removing the higher boiling components from the liquid phase by contacting it with a rising vapor stream. In the context of continuous distillation, the stripping section typically follows the rectifying section. In this section, the liquid entering from the rectifying section (which is enriched in lighter, lower boiling components) is further treated to remove any remaining higher boiling components. The rising vapor stream in the stripping section helps to strip off these high boiling components from the liquid phase, thereby enriching the liquid in lighter components as it moves down the column. This separation process facilitates the production of products with desired specifications in terms of purity and composition. Therefore, in the stripping section of a continuous distillation column, the liquid is indeed stripped of high boilers.
