This study proposes a model of a cyclic distillation tray with separate phase movement (SPM). The model is based on detailed equations for the differential mass balance of the stage during vapor supply, the liquid flow hydrodynamics and the mass transfer kinetics using local point efficiency. Aspen custom modeler (ACM) was chosen for the model implementation due to its rich features as computer aided process engineering tool. ACM has built-in connectivity for the thermodynamics and flowsheeting calculations hence the model allows a straight forward performance evaluation for any binary separation process, filling the gap between design and application of cyclic distillation.
