Modeling of Distillation Processes

“…A complete system of equations describing the film model for distillation of multicomponent systems can be found elsewhere (see, e.g., Refs [52,53]) Along with the equations, this model requires some parameters which must be known a priori. Among these parameters are pressure drop, liquid hold-up, specific interfacial area, mass and heat transfer coefficients and, in some cases, residence time distribution.…”

“…As long as the relevant process and model parameter correlations are available for the specific distillation column under consideration, the film model basically yields predictive and reliable results (e.g., Refs [52,53,79]). …”

Advanced rate‐based simulation tool for reactive distillation

“…The film thickness is an important model parameter that is usually estimated via empirical mass-transfer coefficient correlations allowing for the influence of column internals, hydraulics, and transport properties (Górak, 1995). In the project, the most suitable and reliable correlations for a number of structured and random packings and trays have been chosen from the open literature, thoroughly tested, and implemented into DESIGNER.…”
