Table 1-1 in the textbook provides representative pricing for CSTR and batch reactors. a. Why are the prices of CSTR and batch reactors similar? b. Where are you going to look for the pricing of a tubular reactor? What are the advantages and A CSTR is used when intense agitation is required. Figure 1-7(a) showed disadvantages of a a cutaway view of a Pfaudler CSTR/batch reactor. Table 1-1 gives the typical CSTR? sizes (along with that of the comparable size of a familiar object) and costs for batch and CSTR reactors. All reactors are glass lined and the prices include om hirigits heating/cooling jacket, motor, mixer, and baffles. The reactors can be operated at temperatures between 20 and 450F and at pressures up to 100 psi. TABLE 1-1.

It is relatively easy to maintain good temperature control with a CSTR because it is well mixed. There is, how- ever, the disadvantage that the conversion of reactant per volume of reactor is the smallest of the flow reactors. Consequently, very large reactors are neces
