It is made of different materials which protect the inner chemical reactions from any external interferences.
· Inlet and Outlet Pipes
It also has a pipe on one end that feeds the tubular reactor with all the reactants known as the inlet pipe.
On the other end, we have a release pipe which eliminates the final product after a complete chemical reaction occurs.
· Control System
This type of reactor has a control system which you will use to control all the chemical reaction parameters on the device.
How Do the Tubular Reactors Work?
The tubular reactors work on the principle of continuous flowing systems in a cylindrical geometry.
Here is a brief explanation on how the tubular reactors work.
First you will introduce a fluid or fluids that you intend to mix with other reactants into the tubular reactor.
As the fluids of reactants flow through the tube or tank, there is a chemical reaction that takes place.
This will result in a concentration gradient known as an axial concentration gradient.
As that happens there are particular products that will not react during the reaction process.
On the other hand, there are reactants that will react during the reaction process to form homogenous mixtures.
As soon as the reaction is complete, unreacted products plus the homogenous mixtures will flow out of the tubular reactors.
The process is continuous and does not pose at any moment until you complete the entire reaction process.
What are the Applications of the Tubular Reactors?
