UPL Executive Production Interview Questions and Answers

Q1. What are the differences between the fire point and flash point?
Ans. 
Fire point is the temperature at which a fuel continues to burn after ignition, while flash point is the temperature at which a fuel produces a flammable vapor.
• Fire point is higher than flash point.

• Flash point is the minimum temperature at which a liquid gives off vapor in sufficient concentration to ignite.

• Fire point is the temperature at which a fuel sustains combustion once ignited.

• Flash point is used to classify fl...read more

Q2. What is the difference between flash distillation and fractional distillation?
Ans. 
Flash distillation is a single-stage process where a liquid mixture is vaporized quickly, while fractional distillation is a multi-stage process where the mixture is separated into fractions based on boiling points.
• Flash distillation is a rapid vaporization process used for separating components with large differences in boiling points.

• Fractional distillation is a slower process that involves multiple distillation stag...read more

Q3. What is the difference between "flammable" and "inflammable"?
Ans. 
The terms 'flammable' and 'inflammable' mean the same thing - capable of catching fire easily.
• Both 'flammable' and 'inflammable' mean easily ignited and capable of catching fire.

• The prefix 'in-' in 'inflammable' does not mean 'not' as in other words, but rather intensifies the meaning.

• The use of 'inflammable' can sometimes cause confusion due to the misconception that it means 'not flammable'.

Q7. What is the theoretical plate height in packed bed and distillation columns?
Ans. 
The theoretical plate height in packed bed and distillation columns is a measure of the efficiency of separation.
• The theoretical plate height in packed bed columns is typically calculated using the HETP (Height Equivalent to a Theoretical Plate) equation.

• In distillation columns, the theoretical plate height is a measure of the height of an idealized theoretical plate required for a given separation efficiency.

• Theoretic...read more

Q8. What calculations are required to dilute a sodium hydroxide (NaOH) solution from 12% to 5%, and how much water should be added?
Ans. 
To dilute a 12% NaOH solution to 5%, calculations involve using the formula C1V1 = C2V2 and determining the amount of water needed.
• Use the formula C1V1 = C2V2, where C1 is the initial concentration, V1 is the initial volume, C2 is the final concentration, and V2 is the final volume.

• Calculate the volume of the initial 12% NaOH solution needed using the formula V1 = (C2 * V2) / C1.

• Subtract the initial volume from the fin...read more
