FCC反应过程的CFD模拟进展
CFD modeling of FCC reaction process：a review
摘要
Abstract
Fluid catalytic cracking (FCC) is a crucial conversion process in a petroleum refinery, which produces important chemicals,e.g. gasoline, diesel, light olefins,etc. Computational fluid dynamics (CFD) modeling of FCC reaction processes assists to understand the behaviors of flow and reaction in FCC riser reactors, design and optimize the FCC units, and finally provide the guidance for production and implement the virtual tuning and scale up of processes. This study reviews the recent processes in the multiphase flow models, reaction kinetics and the coupling between flow and FCC reaction. In terms of the coupling approaches, summaries and critical comments are present from the usage of turbulent models, the impact of flow structures, more sophisticated models to crude oil vaporization models. Based on the previous studies, it is pointed out by the authors that although CFD modeling can well reveal the behaviors of flow and reaction in FCC riser reactor of industrial scale, the current theoretical models and modeling techniques have a long way to run up with the experiment counterpart since there is no successful application of CFD reactive modeling of a series of FCC riser reactors ranging from a bench scale to the industrial scale. For the future of FCC reactive modeling, it is very necessary to emphasize the studies on the modeling and the computing efficiency, then strike a balance between them to realize the virtual process engineering.关键词
