Figure 5-2. Continuous Stirred Tank Reactor. CSTR DESIGN EQUATIONS Space Time and Space Velocity concept The space time, τ , is the time required to process one reactor volume of feed and is given by the following equation: Ao Ao o C V V Fv eq 5-36 where C Ao is the initial concentration The volume of a CSTR can be represented as the shaded areas in the Levenspiel Plot shown below: Reactors in Series. Given –r A as a function of conversion, , –r A = f(X), one can also design any sequence of reactors in series provided there are no side streams by defining the overall conversion at any point.

Given –rAas a function of conversion, –rA = f(X), one can size any type of reactor.

Rate Law The rate equation is independent of the type of reactor (e.g. batch or continuous
CSTR Model. The linearized model of a continuous stirred-tank reactor (CSTR) involving an exothermic (heat-generating) reaction is represented by the following differential equations:
Reactor Engineering Methodology • Using Conversion in our Design Equations – CSTR (Single Reaction) – Batch (Single Reaction) – PFR (Single Reaction) – PBR (Single Reaction) • Using Flow/Concentration for Design… – Semi-Continuous (Single and Multiple Reactions) Due to the “Differential Equations” and many species involved…

2020-11-17 · The CSTR design equation gives the reactor volume V necessary to CSTR reduce the entering flow rate of species j from F j0 to the exit flow rate F j, when species j is disappearing at a rate of –r j. We note that the CSTR is modeled such that the conditions in the exit stream (e.g., concentration and temperature) are identical to

Design Equations and Calculations The hippopotamus digestive system is modeled as a CSTR and a PFR in a series. The continuous-stirred tank reactor (or the backmix reactor) is used very commonly in industrial processing and is normally run at steady state. A= C A0(1 X) For batch reactors, conversion is a function of time whereas for ﬂow reactors at steady state it is a functionofvolume 2.2.2 CSTRDesignEquation Using the expression for the volume of a given CSTR derived earlier, we can eliminate F Approach to steady state in a continuous stirred tank reactor (CSTR).
