The plug flow reactor (PFR) model is used to describe
chemical reactions in continuous, flowing systems. The PFR
model is used to predict the behaviour of chemical reactors,
so that key reactor variables, such as the dimensions of the
reactor, can be estimated. PFR's are also sometimes called
Continuous Tubular Reactors (CTR's).

An ideal continuous stirred-tank reactor is based on the
assumption that the flow at the inlet is completely and
instantly mixed into the bulk of the reactor. The reactor
and the outlet fluid have identical, homogeneous
compositions at all times. An ideal CSTR has an exponential
residence time distribution:

Question 36 - For a mixture of benzene (B), toluene (T) and xylene (X), the equation applies where x for B, T and X will sum up to 1. The equation of x for each component is x = (L / V + 1) (F) / (L / V + K). The data of F for each component are : 0.5 for B, 0.35 for T, 0.15 for X. The data of K for each component are : 1.98 for B, 0.76 for T, 0.24 for X. When x for B + x for T + x for X = 1, find the values of (a) L / V; (b) x for each component of B, T, X respectively. You may use Excel program - Data : What-If-Analysis for Goal Seek to perform the iterative calculations.
