Indian Potash HOD Production Interview Questions and Answers

Q1. What is relative volatility
Ans. 
Relative volatility is a measure of how easily a component in a mixture can be separated from other components through distillation.
• Relative volatility is calculated as the ratio of the vapor pressures of the two components being separated.

• It is used in distillation processes to determine the efficiency of separation.

• Higher relative volatility indicates easier separation of components.

• For example, in the separation of ...read more

Q1. What is Distillation
Ans. 
Distillation is a process of separating components of a liquid mixture based on differences in boiling points.
• Distillation involves heating the liquid mixture to create vapor, then cooling the vapor to condense it back into liquid form.

• The components with lower boiling points will vaporize first and be collected, while the components with higher boiling points will remain in liquid form.

• Examples of distillation include...read more

Q2. Difference absorber Column and strippers column
Ans. 
Absorber column absorbs a gas into a liquid, while a stripper column removes a component from a liquid.
• Absorber column is used to absorb a gas into a liquid, while a stripper column is used to remove a component from a liquid.

• Absorber column operates at a higher pressure than the stripper column.

• Absorber column is used in processes like gas sweetening, while stripper column is used in processes like solvent recovery.

• Ex...read more
