Nonsegregated flow

In this chapter, we develop the basis for design and performance analysis for a CSTR (continuous stirred-tank reactor). The general features of a CSTR are outlined in Section 2.3.1, and are illustrated schematically in Figure 2.3 for both a single-stage CSTR and a two-stage CSTR. The essential features, as applied to complete dispersion at the microscopic level, i.e., nonsegregated flow, are recapitulated as follows ... 

For a first-order reaction in a CSTR, compare the predicted performance for completely segregated flow with that for nonsegregated flow.

Powders may be classified as nonsegregating (cohesive) or segregating (free-flowing). Representative samples can be more easily taken from cohesive powders, provided that they have been properly mixed. For wet samples a sticky paste should be created and mixed from which the partial sample is taken.
