Question 3

The upper section of the tower is referred to as:

Accepted Answer

The upper section of a distillation tower is commonly referred to as both the rectifying section and the enriching section, where the concentration of the more volatile component is increased.

Question 4

Condensed tower product that is pumped back into a tower to increase product purity and control temperature:

Accepted Answer

Reflux is the condensed product that is returned to the tower to enhance separation and control temperature, improving product purity.

Question 6

Distillation is best defined by the following statement:

Accepted Answer

Distillation is a process that separates components in a mixture based on differences in their boiling points.

Question 7

The lower section of the tower is referred to as:

Accepted Answer

The lower section of a distillation tower is called the stripping section, where the more volatile components are stripped from the liquid.

Question 8

The tray located below the inlet feed line is called the:

Accepted Answer

The tray located below the inlet feed line in a distillation column is typically referred to as the "feed tray," where the feed mixture is introduced into the column.

Question 9

Each tray in a distillation column has a different molecular structure.

Accepted Answer

Each tray in a distillation column is designed to separate a specific component of the mixture based on its molecular structure and volatility.

Question 17

All of the following are principles of distillation except:

Accepted Answer

Distillation involves the separation of components based on differences in boiling points, not the formation or breaking of molecular bonds.

Question 18

The larger the difference between partial pressures the harder it is to separate the fractions by boiling point.

Accepted Answer

A larger difference in partial pressures typically makes it easier to separate fractions by boiling point, as it indicates a greater volatility difference between the components.
