  2. Continuous stirred-tank reactor - Wikipedia

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

    The continuous stirred-tank reactor (CSTR), also known as vat-or backmix reactor, mixed flow reactor (MFR), or a continuous-flow stirred-tank reactor (CFSTR), is a common model for a chemical reactor in chemical engineering and environmental engineering. A CSTR often refers to a model used to estimate the key unit operation variables when using ...

  3. Levenspiel plot - Wikipedia

    en.wikipedia.org/wiki/Levenspiel_plot

    For a continuous stirred-tank reactor (CSTR), the following relationship applies: [1] [2] = where: is the reactor volume; is the molar flow rate per unit time of the entering reactant A

  4. Chemical reactor - Wikipedia

    en.wikipedia.org/wiki/Chemical_reactor

    Batch reactor model, Continuous stirred-tank reactor model (CSTR), and; Plug flow reactor model (PFR). Many real-world reactors can be modeled as a combination of these basic types. Key process variables include: Residence time (τ, lower case Greek tau) Volume (V) Temperature (T) Pressure (P) Concentrations of chemical species (C 1, C 2, C 3 ...

  5. 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:

  6. Damköhler numbers - Wikipedia

    en.wikipedia.org/wiki/Damköhler_numbers

    From the general mole balance on some species , where for a CSTR steady state and perfect mixing are assumed, + = + = = Assuming a constant volumetric flow rate , which is the case for a liquid reactor or a gas phase reaction with no net generation of moles,

  7. Plug flow reactor model - Wikipedia

    en.wikipedia.org/wiki/Plug_flow_reactor_model

    Schematic diagram of a plug flow reactor. The plug flow reactor model (PFR, sometimes called continuous tubular reactor, CTR, or piston flow reactors) is a model used to describe chemical reactions in continuous, flowing systems of cylindrical geometry.

  8. Chemical reactor materials selection - Wikipedia

    en.wikipedia.org/wiki/Chemical_reactor_materials...

    Chemical reactor materials selection is an important aspect in the design of a chemical reactor.There are four main groups of chemical reactors - CSTR, PFR, semi-batch, and catalytic - with variations on each.

  9. COCO simulator - Wikipedia

    en.wikipedia.org/wiki/COCO_simulator

    The COCO Simulator is a free-of-charge, non-commercial, graphical, modular and CAPE-OPEN compliant, steady-state, sequential simulation process modeling environment. It was originally intended as a test environment for CAPE-OPEN modeling tools but now provides free chemical process simulation for students.
