Plastiblends India Production Engineer Interview Questions and Answers

The plant is a manufacturing facility that produces products through a series of processes.

• The plant has multiple production lines that operate simultaneously

• Raw materials are received and stored in the warehouse before being processed

• The production process involves mixing, heating, cooling, and packaging

• Quality control checks are performed at various stages of the process

• Finished products are stored in the finished go

Mass transfer is the movement of substances from one place to another.

• Mass transfer involves the movement of components in a system due to differences in concentration, pressure, or temperature.

• Examples include the diffusion of gases in air, the separation of components in distillation processes, and the absorption of gases in liquids.

• Mass transfer is important in various industries such as chemical engineering, food p

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

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

• The components with lower boiling points will vaporize first and be collected, while the components with higher boiling points will remain in the liquid phase.

• Common examples of distilla...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

Flash point is the temperature at which a substance gives off enough vapor to ignite momentarily, while fire point is the temperature at which a substance will continue to burn after ignition.

• Flash point is the temperature at which a substance can ignite momentarily when exposed to an ignition source.

• Fire point is the temperature at which a substance will continue to burn after ignition.

• Flash point is typically lower t...read more

Centrifugal pump mechanism involves the conversion of mechanical energy into kinetic energy to increase the fluid's velocity and pressure.

• Centrifugal pump consists of an impeller that rotates to create centrifugal force.

• Fluid enters the pump through the center of the impeller and is flung outwards by centrifugal force.

• The fluid gains kinetic energy and pressure as it moves through the pump.

• The fluid is then discharged ...read more
