A packed bed column is a type of chemical reactor used for separation and purification processes.
Consists of a cylindrical column filled with a packing material
Fluid is passed through the column and interacts with the packing material
Used in various industries such as chemical, pharmaceutical, and food processing
Examples include distillation columns and gas absorption columns
Centrifugal pumps work on the principle of converting rotational kinetic energy into hydrodynamic energy.
The pump has an impeller that rotates and creates a centrifugal force, which pushes the fluid towards the outer edge of the impeller
The fluid then enters the volute casing, where the kinetic energy is converted into pressure energy
The pressure energy then forces the fluid out of the pump and into the piping sys...

- Q2. What is distillation?
- Ans.
Distillation is a process of separating components of a liquid mixture based on their different boiling points.
Distillation involves heating a liquid mixture to vaporize the more volatile components.
The vapor is then cooled and condensed back into a liquid, resulting in the separation of the components.
The component with the lower boiling point will vaporize first and can be collected separately.
Common examples of dist...
- Q3. Which type of distillation?
- Ans.
There are various types of distillation, such as fractional distillation, simple distillation, and vacuum distillation.
Fractional distillation is used to separate mixtures with close boiling points, such as in the separation of different components of crude oil.
Simple distillation is used to separate liquids with significantly different boiling points, such as in the purification of water.
Vacuum distillation is used to...
- Q4. Which type of pump and valve?

- Ans.
Vacuum distillation is a process of separating components of a mixture by boiling it under reduced pressure.
It is used to separate components with high boiling points.
The process involves heating the mixture in a vacuum to lower the boiling point.
The lower pressure also reduces the risk of thermal decomposition.
Vacuum can be created using a vacuum pump or aspirator.
Examples include the separation of crude oil into diff...
