Navin Fluorine International Interview Questions, Process, and Tips

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)

The selection of a pump involves considering factors such as flow rate, head, efficiency, type of fluid, and system requirements.

• Consider the required flow rate and head to determine the pump's performance.

• Evaluate the efficiency of the pump to ensure energy savings.

• Take into account the type of fluid being pumped and its compatibility with the pump materials.

• Consider the system requirements, such as space limitations ...read more

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

PMS in project design engineering stands for Project Management System.

• PMS is a software or tool used to plan, execute, and monitor projects in the field of project design engineering.

• It helps in organizing project tasks, allocating resources, tracking progress, and managing project documentation.

• PMS facilitates collaboration among team members, improves project efficiency, and ensures timely completion.

• Examples of PMS...read more

The methodology to size STHE involves determining the appropriate surface area and heat transfer coefficient.

• Calculate the required heat duty or heat transfer rate.

• Determine the temperature difference between the hot and cold fluids.

• Select the appropriate heat transfer coefficient based on the fluid properties and flow conditions.

• Estimate the overall heat transfer coefficient.

• Calculate the required surface area using t...read more
