Stoichiometry
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
Sizes of the component molecules are approximately equal
Attractive forces between like and unlike molecules are approximately equal
Component molecules are non-polar and no chemical combination or molecular association between unlike molecules takes place in the formation of the solution
