An elementary liquid phase reaction A to products, is taking place in a given reactor. The reaction is first order and if plug flow existed, conversion would be 71.3%. The flow characteristics of the vessel is given by the non-normalized C curve shown below:

 

Time (s): 0  120  240  360  480  600  720  840  960

 

Tracer Conc: 0  6.5  12.5  12.5  10  5  2.5  1  0

 

a.) Find the number of tanks-in-series which will represent the reactor and the conversion expected assuming that the tanks-in-series model holds.

 

b.) Find the conversion by direct application of the tracer curve

 

 

Answers you are supposed to get:

 

a.) j = 4.73 tanks, Xa=0.670

 

b.) Xa= 0.659

Hi,

You need to go back to your textbook, or you may find pointers in Youtube which has tutorials on the subject.

Google "reactors engineering reactors in series"

The only way to make progress is to work hard. 

Let us know your difficulties, someone will help.

 

You should find pointers in the document attached:
