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. WebNov 21, 2024 · A CSTR is a reaction vessel that produces chemicals continuously, as the name implies. In the CSTR, two or more reactants are pumped into a vessel and allowed to react, with the product skimmed or …
