Isothermal HI Reactor
Application ID: 1387
For a perfectly mixed reactor with a predefined constant temperature, the reacting system’s energy balance is not needed to describe the system behavior. The behavior is defined as the composition and the production or consumption of species over time. Furthermore, because the reactor is perfectly mixed, the Reaction Engineering interface can also set up a model even though it has no information about material-transport or energy-transport properties.
This model uses the Reaction Engineering interface default reactor type - a Batch reactor with constant volume. Other predefined reactor types available are the Semibatch reactor, the Continuous stirred tank reactor (CSTR), and the Plug-flow reactor. The purpose of the experiment is to study the composition in the reactor over time and determine how long it takes the system to reach steady state, where it is possible to determine the reaction’s equilibrium constant.
This model example illustrates applications of this type that would nominally be built using the following products:Chemical Reaction Engineering Module
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
