M5.1. Background

The reactant conversion in a chemical reactor is a function of the residence time or its inverse, the space velocity. For an isothermal CSTR, the product concentration can be controlled by manipulating the feed flow rate, which changes the residence time (for a constant volume reactor). The feedback strategy is shown in the schematic diagram shown in Figure M5-1.

Here, we consider a series-parallel reaction of the following form (known as the van de Vusse reaction scheme):

The desired product is the component B, the intermediate component in the series reaction. In this ...
