Material Balance around Operating Line

In any balance in the system, we have

Accumulation = input – output + generation – consumption……… (i)

However, while performing material balance in distillation column, we assume,

  1. Operation is carried out in steady state (i.e. constant volume) ⇒ Accumulation = 0
  2. We assume there is no reaction between components. ⇒ Generation = 0, Consumption = 0
