The novel COMET process for the production of OME 3-5 from MeOH and FA(aq.) solves challenging H 2 O management using a reactive distillation column. main units are state-of-the-art were experimentally demonstrated.

We show how program transformation techniques can be used for the verification of both safety and liveness properties of reactive systems. In particular, we show how the program transformation technique distillation can be used to transform reactive systems specified in a functional language into a simplified form that can subsequently be analysed to verify temporal properties of the systems. E...

The control of an ideal reactive distillation column is compared with that of a similar, but somewhat di2erent, real chemical system, the production of methyl acetate. Similarities and di2erences are observed. Three control structures are evaluated for both systems. A control structure with one internal composition controller and one temperature controller provides e2ective control of both syst...

This contribution aims to present a methodology to model and simulate the reactive dividing wall column (RDWC) using commercial software. Feasibility of separation scheme was established with ASPEN DISTILTM. Simulation of flowsheet configuration was performed with ASPEN HYSYSTM, using the two columns model. The reactive zone hosted by the prefractionator was modelled and simulated as backward f...

Type of packings and characteristics of their geometry can affect the flow behavior in the reactive distillation columns. KATAPAK SP is one the newest modular catalytic structured packings (MCSP) that has been used in the reactive distillation columns, recently. However, there is not any study on the hydrodynamics of this packing by using computational fluid dynamics. In the present work, a 3D ...

In recent years in tegrated processes have attracted considerable attention in both academic research and industrial applications. The integration, for instance of reaction and separation, reduces the degrees of freedom and requires tigh t con trol to operate the processes at optimal conditions. F rom the available number of measurements and input variables, a con trol structure has to be iden ...

Reactive Distillation (RD) is the combination of reaction and distillation in a single vessel (Backhaus, 1921). Over the past two decades, it has emerged as a promising alternative to conventional “reaction followed by separation” processes (Towler & Frey, 2002). The technology is attractive when the reactant-product component relative volatilities allow recycle of reactants into the reactive z...

Rising world fuel prices, the growing demand for energy, and concerns about global warming are the key factors driving renewed interest in renewable energy sources and in bioenergy. Nowadays, the world energy demand has increased significantly due to the global industrialization and increase of population. As a result, the current limited reservoirs will soon be depleted at the current rate of ...
