Navin Fluorine International Interview Questions and Answers

Unit operations involved in cooking include mixing, heating, cooling, and separation processes.

• Mixing ingredients to create a homogeneous mixture (e.g. stirring batter)

• Heating to cook food (e.g. boiling, baking)

• Cooling to set or solidify food (e.g. refrigerating)

• Separation processes like filtering or straining (e.g. separating solids from liquids)

Effective plant operation ensures safety, efficiency, and quality in chemical processing through adherence to protocols and continuous monitoring.

• Follow standard operating procedures (SOPs) to maintain safety and efficiency.

• Regularly monitor equipment for signs of wear or malfunction, such as unusual vibrations or leaks.

• Conduct routine inspections and maintenance to prevent unexpected downtime.

A distillation column is a unit used in chemical processes to separate mixtures into their individual components based on their boiling points.

• Distillation column works on the principle of vapor-liquid equilibrium.

• It consists of a vertical column with multiple trays or packing material.

• A mixture is fed into the column and heated to generate vapor.

• The vapor rises through the column and comes into contact with the liquid...read more

A compressor is a mechanical device that increases the pressure of a gas by reducing its volume.

• Compressors work by using a piston or a rotating impeller to decrease the volume of a gas.

• As the volume decreases, the pressure of the gas increases.

• Compressors are commonly used in refrigeration systems, air conditioning units, and industrial processes.

• Examples of compressors include reciprocating compressors, rotary screw ...read more
