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

Vacuum in a column can be created by using a vacuum pump to remove air and other gases from the column.

• Use a vacuum pump to remove air and other gases from the column

• Ensure all connections are airtight to maintain the vacuum

• Monitor the vacuum level regularly to ensure it is maintained

• Adjust the vacuum pump settings as needed to achieve the desired vacuum level

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
