چکیده

This paper presents a modern modeling approach for reactive distillation processes with potential phase splitting. It is based on a classical model (pseudo-homogeneous) in connection with a robust and reliable phase splitting algorithm (through homotopy-continuation method), performed at each simulation step. Model validation stage and a simple case-study (by applying the new approach to a reactive distillation column for waste water treatment) are also presented. All simulation scenarios revealed a good agreement between simulation results and the real system behavior, much better than using a classical pseudo-homogeneous mathematical model.

A Systematic Approach on the Dynamic Modeling of Reactive Distillation Processes The standard mathematical model (NPHSP)

This work addresses the major problem of reactive distillation (RD) processes mathematical modeling, revealing also why detecting the presence of a three-phase regime (vapour-liquid-liquid) on the column stages is of utmost importance. In this paper, the authors present in detail their starting modeling approach, which describes the behaviour of a “classic” RD process (where the potential liqui...

Dynamics of reactive distillation processes with potential liquid phase splitting based on equilibrium stage models

A dynamic reactive distillation (RD) column model is developed for highly nonideal systems with potential phase splitting. Dynamic simulations and nonlinear dynamic analysis are performed for recovery of acetic acid from waste waters by esterification with n-butanol, which is an interesting alternative to nonreactive separation processes. Two alternative RD column designs were tested with respe...

A Systematic Approach on the Dynamic Modelling of Reactive Distillation Processes with Potential Liquid Phase Splitting. Building-up the improved PHSP simulation model. II

As shown in the first part of our work [1], this paper deals with the presence of a three-phase regime (vapour-liquid-liquid) on the reactive distillation (RD) column stages due to a liquid liquid phase splitting (PHSP) between aqueous and organic phases. Special attention has to be paid on this subject, because detecting the three phase regime can lead to different operating and design strateg...

Hydrodynamics of Sieve Tray Distillation Column Using CFD Simulation

Sieve trays are widely used in the gas- liquid contactors such as distillation and absorption towers. In this article, a three-dimensional, two phase CFD model using Euler-Euler framework was developed to simulate a distillation tower with two sieve trays. Hydrodynamic simulation of air and water system in different rates of gas phase was carried out and velocity distribution parameters, clear ...
