Note: For a CSTR fluid elements have a distribution of residence times since the reactor is completely mixed. Some fluid elements of the input flow leave the reactor immediately while others stay around for infinity. In general θ may be defined as a concentration weighted average time (for a pulse input [see below]).

For a CSTR it may be shown that θ = V/Q as follows: For wash-out of a pulse of a conservative material and t (V /Q) i C C e - = 2 1 t Q/ V i t /(V /Q) Qt ( ) V C e (Q/ V) - - - - 0 0 tCdt Cdt θ = 0 0 0 0 1 i t t /(V /Q) Q/ V i i tC e dt C e dt C e Q/ V - - θ = = θ V/Q 2 1 1 (Q/ V) Q/ V = =

A brief comment on how to compute your residence time. Consider the summation: t C ) j ( n 1 j = This is just the area under the tracer response curve (i.e., the plot of C vs. t) ( 29 3 4 ) C C ( - + C (j) = (C 4 + C 3 )/2 C 1 2 3 4 5 6 Area = 3 4 t t 2 In the summation: t C t ) j ( n 1 j j = t j = (t 4 + t 3 )/2 t (j) Time

PFR and AFR Reactors: Development of Response Equations We'll begin with the most complex case and derive general equations. Later, we will make simplifying assumptions and apply the equations.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
