Q1. What is Reactor types of.Reactor and use
Ans. 
Reactors are vessels used to contain chemical reactions. Types include batch, continuous, and semi-batch reactors.
• Batch reactors are used for small-scale production and testing.

• Continuous reactors operate continuously with a steady flow of reactants and products.

• Semi-batch reactors combine features of both batch and continuous reactors.

• Examples include CSTR (Continuous Stirred Tank Reactor) and PFR (Plug Flow Reactor).

Q4. What is scrubber
Ans. 
A scrubber is a device used to remove pollutants from exhaust gases in industrial processes.
• Scrubbers can be used to remove particulates, gases, or both from emissions.

• There are different types of scrubbers such as wet scrubbers, dry scrubbers, and gas scrubbers.

• Wet scrubbers use a liquid to wash pollutants out of the gas stream, while dry scrubbers use a dry reagent or slurry.

• Examples of scrubbers include sulfur dioxi...read more

Q5. What is distillation and type of distillation
Ans. 
Distillation is a process of separating components of a liquid mixture based on differences in boiling points.
• Distillation involves heating a liquid mixture to create vapor, then cooling the vapor to condense it back into liquid form.

• The condensed liquid is collected separately, resulting in the separation of components based on their boiling points.

• Types of distillation include simple distillation, fractional distilla...read more
