SEPARATION PROCESS PART 1

What is the primary function of separation processes in the chemical and petrochemical industries?

• To synthesize raw materials

• To remove impurities from raw materials and products

• To improve product density

• To mix different chemical compounds

Which of the following is NOT a separation technique?

• Distillation

• Adsorption

• Catalytic cracking

• Extraction

What is the key principle behind distillation?

• Difference in solubility

• Difference in boiling points

• Difference in pressure

• Difference in molecular size

What type of distillation takes feed continuously and separates it into two or more products?

• Batch distillation

• Continuous distillation

• Reactive distillation

• Fractional distillation

What component in a distillation column ensures the vapor-liquid contact necessary for separation?

• Reboiler

• Reflux drum

• Trays

• Condenser

What is the role of the reflux in a distillation column?

• To condense the vapors

• To recycle condensed vapor back into the column for better separation

• To remove impurities from the feed

• To heat the liquid at the bottom of the column

Which section of the distillation column increases the concentration of lighter components?

• Stripping section

• Rectification section

• Reboiler section

• Condensation section

What is the function of a downcomer in a distillation column?

• To allow vapors to rise to the next tray

• To permit liquid to overflow to the next lower tray

• To maintain a constant temperature

• To separate lighter components

What is a characteristic of structured packing material in a distillation column?

• Suitable for large diameter columns

• Made of porous steel only

• Provides a large surface area for vapor-liquid contact

• Recycles liquid within the column

What is the primary function of absorption in the refining industry?

• To increase the boiling point of components

• To separate immiscible liquids

• To remove acid gases from gas mixtures using a liquid absorbent

• To condense gases into liquids
