Chemplast Sanmar Senior Process Engineer Interview Questions and Answers

HE refers to Heat Exchangers and pumps are used to move fluids. Types of HE include shell and tube, plate and frame, and spiral. Types of pumps include centrifugal, positive displacement, and axial flow.

• Heat Exchangers: shell and tube, plate and frame, spiral

• Pumps: centrifugal, positive displacement, axial flow

Different types of pumps and heat exchangers are used in process engineering.

• Types of pumps include centrifugal, positive displacement, and axial flow pumps.

• Heat exchangers can be classified as shell and tube, plate and frame, or air-cooled.

• Pumps are used to transfer fluids in a process while heat exchangers are used to transfer heat between fluids.

• Selection of pumps and heat exchangers depends on the process requireme...read more

There are various types of reactors used in production processes, such as batch reactors, continuous stirred-tank reactors, and plug flow reactors.

• Batch reactors are used for small-scale production and allow for easy control of reaction conditions.

• Continuous stirred-tank reactors are used for continuous production and have good mixing capabilities.

• Plug flow reactors are used for reactions that require a specific reside...read more

Types of distillation columns include batch, continuous, fractional, and steam distillation.

• Batch distillation: Used for small-scale production and involves separating components based on boiling points.

• Continuous distillation: Used for large-scale production and involves a continuous feed of mixture and product removal.

• Fractional distillation: Used to separate components with closer boiling points by creating multiple...read more

Steam ejectors work by using high-pressure steam to create a vacuum for removing gases or vapors from a system.

• Steam is expanded through a nozzle to increase its velocity

• The high-velocity steam entrains the gases or vapors to be removed

• The mixture of steam and gases is then condensed and separated in a diffuser

• The condensed steam is usually discharged to a condenser or a drain
