A butane isomerisation process produces 70 kmole/hr of pure isobutane. A purge stream removed continuously, contains 85% n-butane and 15% impurity (mole%). The feed stream is n-butane containing 1% impurity (mole%). The flow rate of the purge stream will be
3 kmole/hr
4 kmole/hr
5 kmole/hr
6 kmole/hr

0.01*f = p*0.15.

f = p + 70.

(p+70)*.01 = p*0.15.

0.01p + 0.70 = 0.15p.

p = 5.
