Answer to Question #231027 in Chemical Engineering for Lucky

Question

9)At present we have 90% conversion of the liquid feed (n-1. CA0-10 mol/l) to our mixed flow reactor with a recycle of product(R-2). If we shut off the recycle stream, by how much the conversion decreases for the same processing rate?

Answer 1

We are given that at present we have 90% conversion of the liquid feed (n-1. CA0-10 mol/l)

If we stay on the 90% conversion line, we find for N = 2 that kCoτ = 27.5,

 point b Comparing the value of the reaction rate group for N = 1 and N = 2, we find Since V2 = 2V1 the ratio of flow rates becomes.

 Thus, the treatment rate can be raised to 6.6 times the original.

We can demonstrate this as shown below:
