2. Continuous stirred-tank reactor - Wikipedia

   en.wikipedia.org/wiki/Continuous_stirred-tank...

   A CSTR often refers to a model used to estimate the key unit operation variables when using a continuous agitated-tank reactor to reach a specified output. The mathematical model works for all fluids: liquids, gases, and slurries. The behavior of a CSTR is often approximated or modeled by that of an ideal CSTR, which assumes perfect mixing. In ...

3. Plug flow reactor model - Wikipedia

   en.wikipedia.org/wiki/Plug_flow_reactor_model

   The key assumption is that as a plug flows through a PFR, the fluid is perfectly mixed in the radial direction but not in the axial direction (forwards or backwards). Each plug of differential volume is considered as a separate entity, effectively an infinitesimally small continuous stirred tank reactor , limiting to zero volume.

   In this way, a higher efficiency may be obtained, or the size and cost of the PFR may be reduced. A PFR has a higher theoretical efficiency than a CSTR of the same volume. That is, given the same space-time (or residence time), a reaction will proceed to a higher percentage completion in a PFR than in a CSTR.

5. Damköhler numbers - Wikipedia

   en.wikipedia.org/wiki/Damköhler_numbers

   In its most commonly used form, the first Damköhler number (Da I) relates particles' characteristic residence time scale in a fluid region to the reaction timescale. The residence time scale can take the form of a convection time scale, such as volumetric flow rate through the reactor for continuous ( plug flow or stirred tank ) or semibatch ...

7. Attainable region theory - Wikipedia

   en.wikipedia.org/wiki/Attainable_Region_Theory

   A combination of reactors is often termed a reactor structure. An example of the reactors that are considered for this theory are Continuous flow stirred-tank reactor (CSTR) and a Plug flow reactor model (PFR). Knowledge of the AR helps to address two areas in chemical reactor design:
