“…Because of insignificant differences in the simulation results between the two models, , good agreement of EQ-stage model simulations with experimental results in prior studies, , and fewer required parameters, the equilibrium approach was chosen for this study. The tool chosen to build this model was Aspen Custom Modeler (ACM) created by AspenTech, due to its access to broad databases of thermodynamic properties of chemical components and their mixtures, implemented thermodynamic property methods, as well as its already built-in methods of solving nonlinear and linear equations.…”

A dynamic model of batch enzymatic reactive distillation was developed based on equilibrium stage approach. Phenomena within the evaporator, column, and condenser were modeled for nonsteady state operation of the process. A detailed approach to reaction kinetics, including equilibrium limitations, overtime deactivation of the catalyst in different temperatures, diffusional limitations in catalytically active xerogel coating, and temperature influence on the catalyst, was undertaken for ethyl butyrate transesterification with R-2-pentanol with the use of Candida antarctica lipase B as the catalyst. The model was validated with experimental data and served as a simulation tool for sensitivity analysis.

“…For the modelling of reactive distillation in packed columns, both equilibrium stage (EQ) and non-equilibrium stage (NEQ) approaches are used [16]. For esterification processes the simpler EQ models have shown good results in comparison with stationary experimental data [17][18][19]. During the startup of a distillation column the hydraulic variables (flow rates, holdups) and thermodynamic variables (temperatures) undergo large changes [20].…”
