Feasibility Condition for the Conventional Control Structure

Let us consider a reactor/separator/recycle process, where n reactants Aj give m products and intermediates Pk. The network of r reactions can be described by  [Pg.111]

Let us assume that the separation section does not allow reactants Aj to leave the process. Then, the overall mass balance can be written as  [Pg.111]

Obviously, the linear system (4.16) has at least one solution for any vector F0, if the following condition is fulfilled  [Pg.111]

The flow rates of fresh reactants can be set at arbitrary values, but within stoichiometric constraints. Then, the internal flow rates and concentrations adjust themselves in such a way that, for each reactant, the net consumption rate equals the [Pg.111]

In Chapter 9, the butane/butene alkylation for isooctane production is discussed. The reactions can be represented by the following stoichiometry. [Pg.112]
