Purification Technique

What is the primary output of the distillation process?

• Wastewater

• Gas emissions

• Volatile distillate

• Solid residue

Which of the following is a method of water purification that uses ion exchange resin?

• Distillation

• Deionization

• Desalination

• Reverse osmosis

In continuous distillation, what is maintained at a steady state?

• Temperature only

• Only the reflux ratio

• Pressure only

• Feed input rate and output stream rates

What does reverse osmosis require to function effectively?

• Low temperature

• Gravity

• High pressure

• Low salinity

Which of the following components is NOT typically removed during demineralization?

• Water

• Anions

• Impurities

• Cations

What is the role of the reboiler in the distillation process?

• To cool the vapors

• To heat the liquid at the bottom

• To condense the distillate

• To remove impurities

How does reverse osmosis differ from natural osmosis?

• It requires energy

• It occurs without a membrane

• It moves water from high to low concentration

• It does not filter impurities

What is the purpose of the rectifying section in a distillation column?

• To heat the mixture

• To condense the vapors

• To enrich the lighter components

• To remove the least volatile components

Which process is used to remove mineral salts from seawater?

• Desalination

• Deionization

• Demineralization

• Distillation
