Reactors need to be optimally designed in order to have an efficient and safe process. For Chemical Engineers it is important to learn design equations for the different types of reactors available. Below are the design equations for a Batch Reactor:
In a Batch reactor, If -rA is constant within the reactor in terms of concentration and temperature (hence no spatial variations in Cj and T:
When designing a Batch
Reactor, it is very important to consider how long it will take to achieve the
desired conversion.
Now we can calculate the time using the above expression:
If we want to calculate conversion (X) for a constant volume batch reactor, we can use the following equation:
If the volume of the batch reactor varies, like a combustion chamber of a car, we can follow the following expressions:
