## Abstract The operability of azeotropic distillation columns with multiplicity is analysed during start‐up by dynamic simulation. Different steady states can be reached by applying different start‐up configurations and/or policies. The well‐known benzene‐heptane‐acetone (BHA) system is studied. T
Steady-state multiplicity under idealized conditions in a single column, or in a column section with fixed entry conditions at both ends, depends critically on whether the model postulates infinite or finite column length or mass-transfer rates. Like the.multiplicity in a column with infinite mass-t
