mole
A reaction follows the rate expression of r = –kC1.5 . The feed concentration is 1 mole/L and the reaction rate constant k was determined to be 1.0 (L/mole)1/2/h. For a flow rate of 100 L/h,
a. Compute the volume requirement for a completely mixed batch reactor (CMBR) at 95 percent conversion? You should show the unsteady state mass balance equation for CMBR first and then solve for steady state condition.
b) What is the volume requirement for completely mixed flow reactor (CMFR) at 95 percent conversion? You should show the unsteady state mass balance equation for CMFR first and then solve for steady state condition.
c) What is the volume requirement for plug flow reactor (PFR) at 95 percent conversion? You should show the unsteady state mass balance equation for PFR first and then solve for steady state condition.
Use the following nomenclatures for the mass balance equation:
During t-> t+ nabla t, the concentration changes from Co to C
Constant volume of a reactor for CMBR and CMFR: V
For PFR, during t --> t + nabla t, the concentration changes from Co to C and volume change from V to V+nabla V.
Make sure when you assume steady-state conditon, say so clearly.
