Diphenyl carbonate (DPC) is a precursor in the production of polycarbonate, an important engineering thermoplastic with excellent mechanical and optical properties as well as electrical and heat resistance properties. Traditionally, DPC is synthesized by the transesterification reaction of dimethyl carbonate (DMC) and phenol. In the study, phenyl acetate is used instead of phenol to react with ...

KATAPAK-S is a type of structured catalytic packing, which is used in reactive distillation processes. The dry pressure drop characteristic (the pressure drop in the absence of liquid flow) is of significant importance for the investigation of process hydrodynamics. In this paper, the dry pressure drop within the catalyst packed channels of KATAPAK-S has been investigated using Computational Fl...

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...

Advanced reactive distillation technologies (ARDT) are often overlooked during process synthesis due to their complexity. This work proposes the use of operating windows with additional features identify suitable limits for ARDT. Data needed construct thermodynamic properties, kinetic parameters, constraints materials and experimental methods, heuristics. In addition, two new concepts proposed ...

• Method for simultaneous optimisation of reactive distillation design and operation. Based on a superstructure approach. Consideration reaction versus separation characteristics. Investigation industrially relevant systems. A novel methodology the operation complex process, considering number process alternatives (e.g. pre-/side-reactor, side-stripper, additional columns etc.), is presented. T...
