The reaction A(liq)+B(gas)→C(liq)+D(gas) is carried out in a reactor followed by a separator as shown below
Notation:
Molar flow rate of fresh B is FFB
Molar flow rate of A is FA
Molar flow rate of recycle gas is FRG
Mole fraction of B in recycle gas is YRB
Molar flow rate of purge gas is FPG
Molar flow rate of C is FC
Here, FFB=2 mol/s; FA=1 mol/s, FB/FA=5 and A is completely converted.
If YRB=0.3. the ratio of recycle gas to purge gas (FRG/FPG) is
Molar flow rate of fresh B is FFB
Molar flow rate of A is FA
Molar flow rate of recycle gas is FRG
Mole fraction of B in recycle gas is YRB
Molar flow rate of purge gas is FPG
Molar flow rate of C is FC
Here, FFB=2 mol/s; FA=1 mol/s, FB/FA=5 and A is completely converted.
If YRB=0.3. the ratio of recycle gas to purge gas (FRG/FPG) is
Correct : b
