Q1. What is distillation
Ans. 
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 collect the separated components.

• The component with the lower boiling point will vaporize first and be collected, leaving behind the component with the higher boiling point.

• Examples of distillation include the separation...read more

Q3. What is adsorption
Ans. 
Adsorption is the process in which molecules or particles adhere to the surface of a solid or liquid material.
• Adsorption involves the accumulation of molecules or particles on the surface of a material.

• It is a surface phenomenon, different from absorption where a substance is taken into the bulk of another material.

• Examples include the adsorption of pollutants onto activated carbon in water treatment processes.

Q4. What are different types of separation methods
Ans. 
Different types of separation methods include filtration, distillation, chromatography, and centrifugation.
• Filtration: Separates solids from liquids or gases using a porous material.

• Distillation: Separates components based on differences in boiling points.

• Chromatography: Separates components based on their affinity for a stationary phase.

• Centrifugation: Separates components based on differences in density and size.

Q2. Pressure drop in absorption and reactor
Ans. 
Pressure drop in absorption and reactor is influenced by flow rate, viscosity, temperature, and equipment design.
• Pressure drop in absorption is affected by gas flow rate, liquid flow rate, and contact area.

• In a reactor, pressure drop is influenced by reactor size, catalyst activity, and reaction kinetics.

• Higher flow rates and viscosities generally result in higher pressure drops.

• Temperature changes can also impact pres...read more
