Abstract
A method is provided for determining a state of a distillation column having multiple column stages for separating a feed fluid stream into individual fluid components. The state is determined by means of a model in a manner dependent on pressure differences prevailing between adjacent column stages. In the model, both gaseous and liquid flows between adjacent column stages are brought about by the pressure differences prevailing between adjacent column stages. A substance quantity flow characterizing gaseous flow between two column stages is given by {dot over (N)}·R=C·Δp. A substance quantity flow characterizing liquid flow between two column stages is given by {dot over (N)}·R=C·Δp. Δpis a total pressure difference between two adjacent column stages. Ris a coefficient of resistance between two adjacent column stages and Cis a conductance value of flow between two adjacent column stages.
