Question
Transcribed Image Text:Problem 1 The dehydrogenation of a compound (elementary kinetics) is taking place in a
selective membrane reactor under isothermal conditions.
A
B+ ½ C
The reaction is reversible and Kc is the equilibrium constant. The manner in which Kc ( the mass
transfer coefficient at volumetric flow rate vo) increases with flow rate depends upon the flow
geometry and the mass transfer dependence on velocity is given by
KC = kco (v/v) 1/2
And the membrane transport of C is given by keaCc when permeate concentration of C is low.
The following parameter values apply,
k = 0.5 dm³/ kg.min, vo = 50 dm³/min, Kc = 0.5 (kg-mol/dm³) ½
Po 10 atm, FA0= 10 kg-mol/min; a = 0.002 atm/kg
Kco 0.1 dm/min W = 200 kg
1. Compare the calculated output valued of FB, the molar flow rate of B for no pressure
drop.
