Bharat Rasayan Production Supervisor Interview Questions and Answers

Heat exchangers transfer heat between two fluids without mixing them, while condensers convert vapor into liquid by removing heat.

• Heat exchangers transfer heat between two fluids without mixing them

• Condensers convert vapor into liquid by removing heat

• Thermal sock parameters include temperature, pressure, and flow rates

• Temperature is the measure of the average kinetic energy of particles in a substance

• Pressure is the force exerted on a surface per unit area

• Flow rate is the vol...read more

Distillation is a process of separating components of a liquid mixture based on differences in boiling points.

• Distillation involves heating a liquid mixture to create vapor, then cooling the vapor to condense it back into liquid form.

• The condensed liquid is collected separately, resulting in the separation of components based on their boiling points.

• Types of distillation include simple distillation, fractional distillation, and steam distillation.

• Simple distillation is used f...read more

Reactors are vessels used to contain chemical reactions. Types include batch, continuous, and semi-batch reactors.

• Batch reactors are used for small-scale production and testing.

• Continuous reactors operate continuously with a steady flow of reactants and products.

• Semi-batch reactors combine features of both batch and continuous reactors.

• Examples include CSTR (Continuous Stirred Tank Reactor) and PFR (Plug Flow Reactor).

Heat exchangers transfer heat between two or more fluids while keeping them separate.

• Heat exchangers work on the principle of transferring heat from one fluid to another without mixing them

• Types of heat exchangers include shell and tube, plate, and finned tube

• Examples of heat exchangers include radiators in cars and condensers in air conditioning units

A scrubber is a device used to remove pollutants from exhaust gases in industrial processes.

• Scrubbers can be used to remove particulates, gases, or both from emissions.

• There are different types of scrubbers such as wet scrubbers, dry scrubbers, and gas scrubbers.

• Wet scrubbers use a liquid to wash pollutants out of the gas stream, while dry scrubbers use a dry reagent or slurry.

• Examples of scrubbers include sulfur dioxide scrubbers used in coal-fired power plants and scrubbers...read more

Types of reactors include batch, continuous, and semi-batch. Common pumps include centrifugal, positive displacement, and diaphragm. Heat exchangers include shell and tube, plate, and double pipe.

• Types of reactors: batch, continuous, semi-batch

• Common pumps: centrifugal, positive displacement, diaphragm

• Heat exchangers: shell and tube, plate, double pipe

Flammable liquids are substances that ignite easily and burn rapidly. They are commonly used in industrial processes.

• Gasoline

• Acetone

• Ethanol
