Handin 5: Reactor Simulation

This exercise is based on the fed-batch reactor problem described in section 4.2.3. (These notes will pop up in a new window.)

You are advised to use the web DAE solver, so it is suggested you experiment with it first.

A partial model is provided here. This uses a modified version of the web DAE solver. You can save it in your own workspace.

You will have to fill in the equations yourself. See the notes in section 4.2.3 and rewrite the equations in a form appropriate to the solver. (Assume that the molar dansity of all species is 1kmol/m3.)

Confirm that with the given operating conditions, after 4 hours the reactor contains just over 8m3 of material and just less than 5kmol of product.

The idea is to try to find operating conditions for the reactor by choosing a suitable constant feed rate of A, so that at least 85% of all reactants are converted in the 4 hours that are allotted for this step by the plant production schedule. You should not change any other quantities.

Your handin should include a) your model equations, b) your recommended operating conditions and c) a note of the final amounts of A B and C in the reactor.
