Distillation is a process used to separate components of a liquid mixture based on their boiling points.

• Distillation involves heating a liquid mixture to create vapor, then cooling the vapor to collect the separated components.

• Types of distillation include simple distillation, fractional distillation, and steam distillation.

• Simple distillation is used for separating components with significantly different boiling point...read more

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

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

• Shell and tube heat exchangers are commonly used in industrial applications.

• Plate heat exchangers are compact and efficient, often used in HVAC systems.

• Finned tube heat exchangers are used when one fluid has a high heat transfer coefficient.

A pump is a mechanical device used to move fluids from one place to another. There are different types of pumps based on their working principle and application.

• Pumps can be classified into two main types: positive displacement pumps and centrifugal pumps.

• Positive displacement pumps move fluid by trapping a fixed amount and forcing it into a discharge pipe. Examples include piston pumps and diaphragm pumps.

• Centrifugal ...read more
