The F3 consortiums vision is that the EUs chemical industrys competitive position would be strongly enhanced if it could operate modular continuous plant (F3 plant) which combines world scale continuous plant efficiency, consistency and scalability with the versatility of batch operation. Our project will deliver such a radically new production mode based on: a) Plugandplay modular chemical production technology, capable of widespread implementation throughout the chemical industry. This technology uses generic backbone facilities designed for rapid interfacing with standardized process equipment containers (PEC). The PEC house process equipment assemblies (PEA) composed of intensified process equipment for fast, flexible future chemical production b) Holistic process design methodology applying process intensification concepts and innovative decision tools. This will accelerate process development and provides a substantial reduction in energy consumption, raw material usage and plant volumes. Our consortium of leading academic & research institutions and 7 major synthetic chemical producing industrial companies has 3 main goals: 1. To prove the technical feasibility of the F3 mode of manufacturing by building and operating a 0.1 to 30 kg/hr demonstration facility, 2. To demonstrate that operation of F3 plant will be more economical, ecoefficient and more sustainable than conventional production modes like large scale continuous or small to medium scale batch processing. 3. To drive a step change in the technology available to EU chemical production and engineering companies by designing intensified equipment for reaction and down stream processing, dissemination of standards for plug and play modular plant and providing open access to the backbone facility Our estimates indicate that the F3 concept will generate additional new business and will save 3.75 billion euro when existing products change to the F3 mode of manufacture.

Reaction Kinetics, Mechanisms and Catalysis | Year: 2011

The Rh-catalyzed hydrosilylation of acetophenone in the presence of [Rh(CO)2(μ-Cl)]2 and [Rh(COD)Cl]2 complexes, as well as with an in situ addition of nitrogen-containing derivatives of mono- and bicyclic terpenes was investigated in a flow microreactor and in a batch reactor. Kinetic modeling, reaction equilibrium analysis and multi-criteria optimization of the process were applied to compare the performances of the reactors. In general, the highest catalytic activity was reached in the presence of [Rh(COD)Cl]2 and [Rh(CO)2(μ-Cl)]2 without the addition of amines. The best reaction selectivity towards 1-phenylethanol silyl ether with the [Rh(CO)2(μ-Cl)]2 complex was observed in the microreactor. The addition of (R)-(-)-cis- MyrtNH2 and (R)-(+)-BornylNH2 amines, as well as an increase of the amine-to-rhodium molar ratio significantly decreased the conversion and selectivity in both reactors. In this connection, the [Rh(COD)Cl]2 complex demonstrated a better catalytic performance in all cases. The application of the flow microreactor promoted another elementary reaction pathway due to micromixing effects. © AkadÉmiai KiadÓ, Budapest, Hungary 2011.

POLYCAT provides an integrated, coherent and holistic approach utilizing novel polymer based nanoparticulate catalysts in pharmaceutical, crop protection and vitamin syntheses in conjunction with the enabling functions of micro process technology and green solvents such as water or ethyl lactate. This provides a discipline bridging approach between fine chemistry, catalysis and engineering. This will lead to the replacement of a number of chemical or microbiological reaction steps in fine chemical syntheses by catalytic ones using more active, selective and stable nanoparticulate catalysts. In addition, POLYCAT will lead to the development of novel chiral modifiers immobilized on the polymeric supports. Micro process technology provides testing under almost ideal processing conditions, with much improved heat management, with improved costing, at high data validity, at high process confidence, and with high certainty for scale-out. The industrial applicability is demonstrated by scale-out of the industrial demonstration reactions to the pilot scale. A multi-purpose, container-type plant infrastructure will integrate individual reaction and separation modules in block format, standardised basic logistics, process control, safety installations, and on-line analytics. As guidance before (ex-ante) and during the whole development, holistic life cycle (LCA) and cost analyses will pave directions towards competitiveness and sustainability. The POLYCAT technologies have potential to reduce the environmental impact by 20% up to orders of magnitude: e.g. reduction of green house gas emissions, acids (SO2-Eq.), nutrients (NOx-Eq.), toxic substances (1,4-DCB Eq.) and finite abiotic resources (antimony eq.). With (enantio)selectivity increases up to 25%, solvent reductions of 30-100%, and products cost decreases of about 10%, a midterm impact of 30-110 Mio Euro and longterm impact of 100-560 Mio Euro result.

Modular process engineering, e.g., container plants, opens interesting new perspectives for production plants of chemical and pharmaceutical processes. Modular micro and millireactors for container plants are actually in the phase of being introduced or established in the market of process technologies. Reference examples in production scale are still missing. The technology platform of micro and millireactors fulfills the demands of container plants. This is demonstrated for selected equipment. © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Contacting and separation of immiscible fluids in chemical synthesis is important for both reaction step as well as the post processing procedure. The importance of microstructured devices is due to their potential to provide short diffusion paths and high specific surfaces. In contrast to apparatus for single phase applications, which have been studied broadly, systematical research on microstructured dispersing devices and separators is still at its beginning. This paper focuses on the suitability of selected micromixers and hydrocyclons for multiphase applications. © 2011 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.

An apparatus with rectangular product channels and static mixing elements for process intensification is investigated in terms of heat transfer and hydrodynamics. Herringbone-like static mixing elements increase the overall heat transfer coefficient significantly, and the stall angle was found to have a major influence on hydrodynamics and heat transfer. The knowledge of structural parameters of the mixing elements is crucial for apparatus design and prediction of the apparatus performance. A method to derive mean structural parameters from experimental results is presented. Reactors on a milli-scale open the possibility to develop modular equipment that allows for flexible production. An apparatus with rectangular product channels and mixing elements for process intensification is investigated in terms of hydrodynamics and heat transfer. The apparatus performs competitively with established reactor concepts and is, thus, an alternative for modular production units. Copyright © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Continuous high-intensity mixing of two fluids for carrying out fast precipitation is an important method for producing nanoparticulate solids for diverse applications, e.g., in fine chemistry, pigment or catalyst preparation. Continuous precipitation with a newly developed micromixer technology, the so-called valve-assisted micromixer, allows for stable operation without clogging for several days. Scale-up to technically relevant scale was achieved without differences in the quality of the precipitate. The technology has been extensively tested for preparation of catalysts for production of carbon nanotubes. © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
