BRIDGES BETWEEN INDUSTRIAL PRACTICE AND FUNDAMENTAL RESEARCH IN FLUIDIZATION TECHNOLOGY

摘要

A gap exists between industrial practice and fundamental research which has developed since the introduction of fluidization technology in the late 40's of the last century.In industry existing processes are improved and new processes are developed in a more or less empirical way while in academia the focus is on the understanding of underlying physical and chemical mechanisms.In the present paper different ways to bridge this gap are highlighted.One way is that experience from fundamental research work can be brought to industry in the form of measurement techniques and industry-supporting cold-model work.Another solid bridge is developing in the simulation of large-scale reactors.In fundamental research new models have been developed which together with special software and high computing power are ready to help industry with the optimization of existing and the development of new fluidized bed reactors.Finally, process simulation is identified as a field which provides many chances for bridging the gap.In fundamental research tools for flowsheeting are being developed which can be used for solids processes in the same way as existing tools for fluid processes.They can be applied in industry to simulate complex solids processes which consist of a multitude of process units.Recent work on a multiscale based approach to process simulation is promising a more reliable description of process units.
