Coarse-Grid Eulerian-Eulerian Multiphase Model for Fluid Catalytic Cracking Unit

流化催化裂化（FCC）装置是重要的炼油装置操作，占总汽油产量的约45%。这项研究的目的是提高澳大利亚炼油厂的汽油生产效率，从而使我国不仅能够保持自给自足，而且能够进行利润丰厚的出口。这将通过优化催化裂化装置的性能，通过新的计算流体动力学模拟来完成。这项研究的结果将使炼油厂能够生产更清洁的燃料（例如，该技术可减少含硫量较少的燃料），并减少FCC装置的空气污染（以一氧化碳和颗粒物的形式），从而帮助澳大利亚保护其多样化和相对无污染的环境。

A fluid catalytic cracking (FCC) unit is an important refinery unit operation responsible for about 45% of total petrol production. The aim of this study is to improve the petrol production efficiency of Australian refineries thus allowing our country not only to maintain its self-sufficiency but also to permit lucrative exports. This will be done by optimising the performance of the FCC unit through novel computational fluid dynamic simulations. The outcomes of this study will enable refiners to produce cleaner fuel (e.g., fuel with less sulphur) and decrease air pollution from the FCC unit (in the form of CO and particulates) thus helping Australia to preserve its diverse and relatively pollution-free environment.
