Simulation Studies of Reactive Distillation for Ethyl Acetate Production
Reactive distillation is an attractive option for equilibrium limited reactions. For highly nonideal systems, the selection of liquid phase activity model considerably influences the model predictions. In this work, activity models proposed in literature and available in RADFRAC module of Aspen Plus are compared for ethyl acetate production through reactive distillation. Also, a hybrid modellin...
متن کاملReview Modeling of Reactive Distillation Column for the Production of Ethyl Acetate through Esterification
Reactive distillation is the combination of reaction and separation in a same column. It is an attractive option whenever liquid phase reactant is in large excess. The energy requirement of the conventional column is very high and requires large recycling costs. RD column works close to the stoichiometric feed conditions thereby eliminating recycling costs and increases the efficiency of the co...
متن کاملReactive distillation for methyl acetate production
We describe a hierarchy of methods, models, and calculation techniques that support the design of reactive distillation columns. The models require increasingly sophisticated data needs as the hierarchy is implemented. The approach is illustrated for the production of methyl acetate because of its commercial importance, and because of the availability of adequate published data for comparison. ...
متن کاملMultistep model predictive control of ethyl acetate reactive distillation column
An unconstrained model predictive control (MPC) strategy is presented for single input-single output (SISO) control of a reactive distillation column. The predictive model of the MPC is based on the autoregressive moving average (ARX) model structure, whose parameters are updated on-line using the process measurement information. The design and performance of the control strategy is evaluated b...
متن کاملDesigning reactive distillation processes: present and future
The potential benefits of applying reactive distillation (RD) processes are taxed by significant complexities in process development and design. The design problem is formulated in the wider context of process development and engineering. From that perspective design methods for RD units developed over the last decades are classified and described. A fingerprint of the most representative work ...
