Webexample, batch reactors have the advantage of being very flexible, but have the disadvantage of being labor intensive. A CSTR, in contrast to a batch reactor, operates continuously. As such, CSTRs are well suited to making very large quantities of product. Other distinguishing features of a steady-state CSTR include the following. WebBatch Reactors vs. Continuous Stirred Tank Reactors (CSTRs) In general, reactors can be classified as either batch or semi-batch reactors (Fig. 2) or continuous reactors. Batch …
