A Continuous Stirred-Tank Reactor (CSTR) is a chemical reaction vessel in which an impeller continuously stirs the contents ensuring proper mixing of the reagents to achieve a specific output (Figure \(\PageIndex{1}\)). Useful in most all chemical processes, it is a cornerstone to the Chemical Engineering toolkit. Proper knowledge of how to manipulate the equations for control of Debasree Ghosh, Lecture notes on Polymer Reaction Engineering, Module II: Design of Ideal Reactors Performance equation of CSTR • The fluid inside the vessel is uniformly mixed (and hence elements of fluid are uniformly distributed), all fluid elements have equal probability of leaving the vessel in the output stream at any time.

Another alternative would be to add an argument 'input.data.frame' that would be used in place of CSTR2in when present. Then we derive design equations for batch reactor (BR), for the ideally mixed continuous stirred tank reactor (CSTR) and for the plug flow reactor (PFR).

to time (may or may not be a linear equation). A common need in engineering calculations is to integrate an equation over some range to determine the total change. For example, say we know the volumetric flow changes with time according to \(d u/dt = \alpha t\), where \(\alpha = 1\) L/min and we want to know how much liquid flows into a tank over 10 minutes if the volumetric flowrate is \( u_0 = 5\) L/min at \(t=0\). To solve the CSTR equations for another set of inputs, the easiest modification might be to change CSTR2in to return the desired inputs. Another alternative would be to add an argument 'input.data.frame' that would be used in place of CSTR2in when present. Then we derive design equations for batch reactor (BR), for the ideally mixed continuous stirred tank reactor (CSTR) and for the plug flow reactor (PFR). Finally This lecture covers: Reactions in a perfectly stirred tank.

a CSTR is shown in the Fig. 1. This plant performs an exothermic chemical reaction from reactant A to product B (A → B). The CSTR from Fig. 1 has a recirculation ﬂow in the jacket, allowing to improve its controller design (Bequette, 2002). The state equations of CSTR are presented in two subsystems as follows: ˆ dTj dt = Fjf Vj (Tjf −Tj Design Eq’n: A dV rA dX F 0 ⋅ =− In the absence of pressure drop or heat exchange, integral form of the design equation is used: = ⋅∫− X A A r dX V F 0 0 Pressure Drop in Reactors In liquid-phase rxns, the conc’n of reactants is not effected by the changes in pressure.
