Satyesh Brinechem Production Engineer Interview Questions and Answers

Unit operations involve physical changes in the material, while unit processes involve chemical changes.

• Unit operations involve physical processes like mixing, crushing, distillation, filtration, etc.

• Unit processes involve chemical reactions like oxidation, reduction, hydrolysis, etc.

• Unit operations are usually used in the initial stages of production, while unit processes are used in the later stages.

• Unit operations f...read more

Types of reactors include batch reactors, continuous stirred-tank reactors, plug flow reactors, and fluidized bed reactors.

• Batch reactors: Used for small-scale production and testing.

• Continuous stirred-tank reactors: Ideal for continuous production with uniform mixing.

• Plug flow reactors: Allow for efficient heat transfer and minimal back-mixing.

• Fluidized bed reactors: Suitable for high-temperature reactions and catalys

Types of agitators include paddle agitators, anchor agitators, turbine agitators, and propeller agitators.

• Paddle agitators are used for low viscosity fluids and gentle mixing.

• Anchor agitators are used for viscous fluids and provide good radial mixing.

• Turbine agitators are used for high viscosity fluids and provide high shear mixing.

• Propeller agitators are used for low viscosity fluids and provide axial flow mixing.

Gas drying is used to remove moisture from gases, while steam drying is used to remove moisture from solids or liquids.

• Gas drying involves passing a gas stream through a desiccant material to remove moisture, commonly used in natural gas processing.

• Steam drying involves using steam to evaporate moisture from solids or liquids, commonly used in food processing or paper production.

• Gas drying is more suitable for removing...read more

Heat exchangers are devices used to transfer heat between two or more fluids at different temperatures.

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

• Shell and tube heat exchangers consist of a shell with tubes running through it, allowing one fluid to flow through the tubes while another flows over the tubes.

• Plate heat exchangers use metal plates to transfer hea...read more
