Intermediate Storage (Storage Shown as Circles; Number Identifies Individual Tanks for Each
Intermediate Product)

Table 3.2 Equipment Times (in Hours) Required for Products A, B, and C

Without intermediate product storage, the shortest multiproduct campaign, as given by Equation (3.6), is
14 h, as shown in Figure 3.7. However, if the materials leaving the reactor and crystallizer are placed in
storage prior to transfer to the crystallizer and dryer, respectively, then this time is reduced to 11 h. The
limiting cycle time for a uis-process is given by
