Arranging Continuous Stirred-Tank Reactors (CSTR's)
Please see the attached file for the fully formatted problem(s). Problem: Two stirred tank reactors are available at a chemical plant, one of volume 100 m3 and the other of volume 30 m3. It is suggested that these tanks be used as a two stage CSTR for carrying out an irreversible liquid phase reaction, A + B Products. The two reactants only will be present in the feed stream in equimolar amounts, CAo = CBo = 1.5 gmol/lit. The volumetric feed rate will be 20 lit/min. The reaction is first order with respect to each of the reactants A and B i.e., second order overall. The rate constant is 0.011 lit/ (gmol.min). a. Which tank should be used as the first stage for higher overall co... click for more

PFR (Pug Flow Reactor) and CSTR (Continuous Stirred Tank Reactor) in Parallel
Please see the attached file for the fully formatted problem(s). An elementary liquid phase reaction (irreversible first order) A ---> R, takes place in a PFR and the conversion is 96%. If a mixed flow reactor of 10 times as large as the PFR is hooked up in parallel with the existing unit, by what fraction could the production be increased for the same 96% conversion?

Continuous Stirred Tank Reactor (CSTR) and Plug Flow Reactor (PFR) Comparison
Please see the attached file for the fully formatted problem(s). 1. Calculate the volume of a CSTR and of a PFR needed to convert 10 L/min of a 2.0 M solution of A to a concentration of 0.1 M. The reaction is A --> B, the rate law is -r = k CA, where k is 0.01667 sec-1. Which is larger? Why? 2. For the reaction given in problem 2, calculate (and graph on one graph) time versus CA/CA0 from 1 to 0.001 for a constant volume batch reactor.
