CSTRs facilitate rapid dilution of reagents through mixing. Therefore, for non-zero-order reactions, the low concentration of reagent in the reactor means a CSTR will be less efficient at removing the reagent compared to a PFR with the same residence time. Therefore, CSTRs are typically larger than PFRs, which may be a challenge in applications where space is limited. However, one of th… sighup received fivemWebA CSTR is treating a wastewater to remove a toxic compound. The reaction is first order with a rate constant of 0.4/minute.
