Objectives and content
The European Process Industry as well as related industries have an immediate need of new design methods for large-scale gas-liquid reactors that are applicable to a wide range of operating conditions and are accurately predictable in the design of new reactor types. The main benefits of such new design tools include:
- Fast and low cost design. screening, and scale-up of new reactors due to fewer experiments
- Better understanding of process leading to higher yield, higher selectivity, reduced waste, and environmentally-safer reactors - Better process control for increased safety and production quality
With the recent appearance of detailed hydrodynamic models for two-phase flow in Computational Fluid Dynamics (CFD) and the increasing availability of powerful computers, there is a clear trend for CFD computer codes to become the future tool for modelling gas-liquid flow with reaction. The objective of this project is to develop such a CFD programme tool for the design of gas-liquid reactors in the bubbly flow regime and to test and improve its capability with a number of industrially relevant examples. The proposed work includes:
- Development of new mathematical algorithms for the adaption of CFD-codes to two-phase bubble flow
- Development of new physical models for turbulence, interfacial region, bubble size distribution, packings. and chemical reaction in gas-liquid bubble flow reactors
- Experimental work on two-phase hydrodynamics, heat and mass transfer, and reaction using advanced experimental techniques (LDA, PDA, laser PIV, etc.) - Validation of the developed models through detailed comparison with experimental results
- Application of the models to a selection of industrially relevant test cases
The consortium comprises several chemical companies which provide large scale experimental facilities in their R&D centres and will be the end-users of the developed tools (DSM, BASF, Kemira, Argon, EniChem), universities with a strong background in related research (Milan, Porto, Stuttgart) and an European research institute (JRC) as R&D performers, as well as a major CFD-software house (AEA).
