Question

The chemical reactor is the center of the process where the engineer can be used, simultaneously, the principles of fluid mechanics, heat transport, mass transport, such as kinetics chemistry and thermodynamics. In general, the mathematical model of reactors starts from mass balances, component and energy. In a simplified way, these balances can be written as:

Mass balance: Accumulate = In – Out

Component balance: Accumulate = In – Out + React

In the case where the reactor operation is non-isothermal, it is necessary, in addition to the balances of mass and component, the energy balance.

Energy balance: Accumulate = In – Out + Generate + Swap

Do global energy balance for a CSTR reactor.
