Abstract: “A method for the modeling of a seepage catalytic packing internal (SCPI) in a catalytic distillation column was developed and applied to the simulation of a catalytic distillation (CD) process. Based on the structure of the internal, rigorous mathematical models consisting of differential algebraic equations were developed to predict the temperature and composition profiles in the CD column. Based on the gPROMS platform, the gPROMS language was used to compile three modules, one for the reaction and the other two modules for hydrodynamic calculations and heat and mass transport calculations. In addition, a graphical user interface (GUI) design and the corresponding port design were implemented for each unit module to clearly represent the flow-sheet of the catalytic distillation process…”

Comments: the authors used an Aspen Properties Property Package to supply thermodynamic properties to the gPROMS models they developed to simulate a catalytic distillation process. Even if the authors were faced with a lack of molecular diffusivity coefficients from Aspen Properties, they provided their own model for that property and were able to get a gPROMS model coded in a very general form. This work is another example of how the CAPE-OPEN Thermodynamic socket in gPROMS let modellers use the thermodynamic model of their choice in gPROMS.
