Q3. Cryogenic distillation
Add your answer

It was 1 hour 45 min test where 40 question from technical side and 50 questions from aptitude. My engineering was chemical engineering so in technical part there were questions from different semester subjects like fluid operation, mass transfer, thermodynamics etc.
In case of aptitude it was logical reasoning, verbal reasoning, algebra. The aptitude was quite moderate level and technical was easy in my opinion.

Q3. What do you know by distillation?
Ans. 
Distillation is a process of separating components of a mixture based on their boiling points.
• It involves heating the mixture to vaporize the component with the lowest boiling point.

• The vapor is then condensed and collected as a separate liquid.

• This process is commonly used in the production of alcoholic beverages, fuels, and essential oils.

• Fractional distillation is a variation of distillation that is used to separate...read more

Q4. What is the significance of relative volatility?
Ans. 
Relative volatility is a measure of the difference in vapor pressures of two components in a mixture.
• It is used in distillation processes to determine the separation efficiency of a mixture.

• Higher relative volatility indicates easier separation of components.

• It is calculated as the ratio of vapor pressures of the two components.

• For example, in the separation of ethanol and water, ethanol has a higher relative volatilit

Q5. What happens when relative volatility is equal to 1. Does distillation is possible during this situation.
Ans. 
Equal relative volatility means no separation is possible in distillation.
• Relative volatility is the ratio of vapor pressures of two components in a mixture.

• When it is equal to 1, the vapor pressures of both components are equal.

• This means they will boil and condense at the same temperature, making separation impossible.

• Distillation relies on the difference in boiling points of components to separate them.

• Therefore, di...read more

Q6. Explain extractive distillation
Ans. 
Extractive distillation is a process used to separate two or more components from a mixture using a solvent.
• It involves adding a solvent to the mixture to form two liquid phases.

• The solvent selectively removes one component from the mixture, leaving the other behind.

• The solvent and the removed component are then separated from each other by distillation.

• Examples include separating ethanol from water using benzene as a ...read more

Q7. Define types of NPSH. State the difference between the type
Ans. 
Types of NPSH and their differences
• Net Positive Suction Head (NPSH) is the difference between the absolute pressure at the pump suction and the vapor pressure of the liquid being pumped.

• Types of NPSH are available NPSH (NPSHa) and required NPSH (NPSHr).

• NPSHa is the amount of NPSH available at the pump suction, while NPSHr is the amount of NPSH required by the pump.

• The difference between NPSHa and NPSHr determines wheth...read more

Q8. How to increase NPSHr when your NPSHa is more than NPSHr
Ans. 
To increase NPSHr when NPSHa is more, reduce the impeller diameter or increase the speed of the pump.
• Reduce impeller diameter

• Increase pump speed
