Semibatch Polymerization

Application ID: 1403

As reactant monomer converts into polymer chains, the density of the reacting mixture often changes notably. In this example you will look at how this effect impacts the total production of polymer in a process. The liquid phase polymerization takes place in a semibatch reactor, where two operating conditions are compared.

In the first scenario, the feed of monomer to the reactor is turned off once the maximum volume capacity is reached. In a second scenario, the feed of monomer is allowed to continuously compensate for the volume change due to chemical reaction.

The model illustrates the use of the Semibatch reactor type, that is predefined in the Reaction Engineering interface. It is also shown how to set timed events, in this case, controlling the reactant feed to the reactor.

This model is included as an example in the following products:
