CDP12-F_B

The degree of backmixing in a tall slurry reactor was analyzed by injecting a pulse of methyl orange into a column (presented in the AIChE Los Angelas meeting, November 1982). for a superficial gas velocity of 10 cm/s and a liquid velocity of 3 cm/s:

Note that no units are specified in the tracer concentration values.

1. What is the mean residence time of a liquid molecule in the reactor?
   
   
2. Develop a model that is consistant with the experimental data. Evaluate all model parameters.
   
   
3. Using the data in Example 12-1, calculate the conversion of methyl linoleate that can be achieved under the same conditions as those of the tracer test. The reaction operating conditions are the same as those given in Example 12-1.
