Process design deals with synthesis and optimization tasks, where process synthesis means to conceive a set of processing units and the interconnections between these units which will fulfill the performance target of the process, and optimization means the evaluation of the best set of parameter values of the system. The intensive use of modular simulators, e.g. ASPEN PLUS or numerical solver ...

Tertiary-amyl methyl ether (TAME) is a potential gasoline additive that can be advantageously synthesized using the reactive distillation (RD) technology. This work emphasizes on non-linear effects in dynamic simulations of reactive distillation column. For certain configurations, dynamic simulation with equilibrium stage (EQ) model leads to sustained oscillations (limit cycles) which have been...

In the present study, two distinctly different approaches are followed for modeling of reactive distillation column, the equilibrium stage model and the nonequilibrium stage model. These models are simulated with a computer code developed in the present study using MATLAB programming. In the equilibrium stage models, the vapor and liquid phases are assumed to be in equilibrium and allowance is ...

High yielded and selective synthesis of macrocyclic unsaturated musk compounds from unbiased dienes using reactive distillation at high concentration.

This work has been carried out to demonstrate the performances of four different state space models in the model predictive control system of a reactive distillation process that was used for the production of ethyl acetate. The state space models of the reactive distillation process were developed with the aid of System Identification Toolbox of MATLAB using the data acquired from the reactive...
