The molar feed of component A to the system is 1 mol/s and the concentration of A in the feed is 1 mol/l. These equations can also be written in another form: [tex]\frac{dC}{dt}=r[/tex] where t =x/v is the cumulative residence time from the inlet to the reactor x = 0 to some arbitrary location x. In this form, you can recognize the equation as the same as for a batch reactor. In contrast, complete mixing in a CSTR reactor produces the tracer concentration throughout the reactor to be the same as the effluent concentration. In other words, in an ideal CSTR, at any travel time, the concentration down the reactor is identical to the composition within the CSTR (Hoboken et al., 2005).

The design equations are derived in terms of intermediate substrate concentrations, operating temperature, enzyme deactivation and the kinetic parameters within each reactor.

Type 3 Home Problem Problems that are over-specified. To derive the CSTR design equation, we begin with the general mole balance: Assuming that the tank is well-mixed and the reaction rate is constant throughout the reactor, the mole balance can be written: . This equation can then be rearranged to find the volume of the CSTR based on the flow rates and the reaction rate:

Two tanks in series. The output of the first tank is the input of the second tank. Chapter 6: Isothermal Reactor Design: Molar Flow Rates Professional Reference Shelf The following information is taken from the 4th edition of Elements of Chemical Reaction Engineering, so the equation numbers correspond to those found in that book Startup of a CSTR The design equations for contiuous stirred-tank reactors (CSTRs) are applicable to chemostats.
