CSTR parallel arrangement

We have considered two types of ideal flow reactor the piston flow reactor and the perfectly mixed CSTR. These two ideal types can be connected together in a variety of series and parallel arrangements to give composite reactors that are... 

A particular vessel behavior sometimes can be modelled as a series or parallel arrangement of simpler elements, for example, some combination of a PFR and a CSTR. Such elements can be combined mathematically through their transfer functions which relate the Laplace transforms of input and output signals. In the simplest case the transfer function is obtained by transforming the linear differential equation of the process. The transfer function relation is... 

The rate of production of intermediate product B in the flnal exit stream of each conflguration has been calculated for the five cases described above. When two CSTRs are arranged in parallel, both exit streams contribute to the overall rate of production. In units of moles of B per minute, five correct answers and two incorrect answer for totaiCu are... 

CSTRs in parallel. For two 800-gal CSTRs arranged in parallel with 7.67 ftVmin (Vo/2) fed to each reactor, the conversion achieved can be calculated from... 

Conversion in the series arrangement is greater than in parallel for CSTRs. 

Problem P5-2(b) asks you to generalize the result for n equal size rectors V, in parallel with equal feed rates (F, (i/n) and show that the conversion would al.so be the same if everything were fed to one big reactor of volume V = nV (c) CSTRs in series. If the 800-gal reactors are arranged in series, the conversion in the first reactor (cf. Equation (E5-2.5)] is...
