The reaction A→B is to be carried out isothermally in a continuous-flow reactor. Calculate the PFR volume to consume 99% of A (CA = 0.01CA0) when the entering molar flow rate is 5 mol/h (assume pure A), the volumetric flow rate is constant at 10 dm3 /h and the rate is: -rA=3CA 2 [ dm3 /mol•h]

Explanation:

From the information above:

The equation for the reactor volume of CSTR is given by the formula:

The reaction rate of A is:

and k = 3 dm³/mol.h

replacing the values in the above equation to solve for v;

∴

V = 66,000 dm³

Thus, the reactor volume of CSTR is 66000 dm³

Taking the differential mole balance equation for PFR is as follows:

Taking the integral between initial and final concentrations;

replace the values in the above equation;

Thus, the reactor volume of PFR is 660 dm³

the dissolution of polymer can be thermodynamically described in 2 steps.
