Simulation of the Chemical Reactor

The model for the chemical reactor was given in Eqns. (6.3) and (6.4) and will be repeated 

The linearized model, relating changes in the reactor flow to changes in the concentration of component A, could be given by  

The steady-state values in Eqns. (8.4) and (8.5) are given in the previous chapter, they are defined in F0809par.m. 

Since the exponent of the temperature is calculated twice, a separate block is created that performs this calculation. This is shown in Fig. 8.7, when it is created, position the cursor in the top left comer, press the left mouse button and draw a box around the blocks while leaving the input T and output exp(-E // 7) outside the box. 

This will result in a subsystem being created which can be renamed, for example to exponent. The text under each operation or block can be modified by double clicking the text box, selecting the text and retyping it. For example, the input name constant can easily be modified to T.

As many other industries, the fine chemical industry is characterized by strong pressures to decrease the time-to-market. New methods for the early screening of chemical reaction kinetics are needed (Heinzle and Hungerbiihler, 1997). Based on the data elaborated, the digital simulation of the chemical reactors is possible. The design of optimal feeding profiles to maximize predefined profit functions and the related assessment of critical reactor behavior is thus possible, as seen in the simulation examples RUN and SELCONT.
