Efficient Approximate Method for Packed Column Separation Performance Simulation

چکیده
Packed distillation and absorption columns are often modeled using equilibrium stages. However, determination of the packing height that corresponds to an equilibrium stage is not easy. For binary systems HETP values can be used, but these are not applicable to multicomponent systems because mass transfer rates of different components deviate from each other. Rate-based non-equilibrium models can be used to overcome the problem of the HETP + equilibrium stage calculation method. Our efficient and approximate approach is different. It uses an equilibrium stage model with multicomponent efficiency factors for a certain packing height. These efficiencies are comparable to the multicomponent Murphree vapor phase efficiencies used for plate columns.
