WebSeveral conclusions can be drawn from this Demonstration: (1) for fixed values of the mixing time and the reactor residence time, the segregation intensity will be higher for the CSTR, due to the fact that mixing is better … WebGeneral Information. Continuous stirred-tank reactors (CSTRs) are open systems, where the material is free to enter or exit the system, that operate on a steady-state basis, where the conditions in the reactor don’t change with time. Reactants are continuously introduced into the reactor, while products are continuously removed.
