| Abstract (English): | A numerical simulation is conducted using computational fluid dynamics (CFD) software Fluent to analyze the regenerator of a 0.65 MM TPY coaxial-type FCC unit. Taking the industrial regenerator as the object, a fully structured modeling is carried out based on its three-dimensional real structure and actual geometric dimensions. The model fully integrates internal and external heat extractors, two-stage series cyclone separators, main air distribution plates, and distributors of catalysts to be generated and regenerated. In the gas-solid two-phase flow model, the user-defined function (UDF) is used to realize the dynamic calculation of the return amount of the spin separation leg, and the return rate is controlled by the preset separation efficiency function to determine the catalyst flow from the spin separation leg into the dense phase bed. Based on the Arbel charring kinetics model, and the distribution coefficient is introduced to characterize the promoting effect of combustion promoter on CO combustion, which significantly improved the accuracy of the model. Calculations show that the calculated density of the catalyst bed at axial heights of 4 m, 12 m, and 20 m is consistent with the actual height values. The relative error between other major parameters, such as the carbon content of the regenerant, the temperature of the regenerant, the temperature of the flue gas, and the molar composition of the flue gas, and the actual value is no more than 5%, indicating that the established model and the carried out calculations are correct and the analysis conclusion is reliable.

| Abstract (Chinese): | 运用计算流体力学 (CFD) 软件 Fluent, 对某 650kt/ a 同轴式催化裂化装置再生器开展了数值模拟研究。以工业再生器为对象, 依据其三维真实结构与实际几何尺寸进行全结构化建模, 模型内完整集成了内外取热器、两级串联旋风分离器、主风分布管、待生催化剂分配器及再生催化剂分配器。在气固流动模拟中, 采用自定义函数 (UDF) 实现旋风分离器料腿返料量的动态计算, 其返料速率由预设的分离效率函数控制, 以确定由旋风分离器料腿进入密相床层的催化剂流量。在 Arbel 烧焦动力学模型基础上, 新增 3 个反应路径, 并引入分配系数以表征助燃剂对 CO 燃烧的促进作用, 显著提升了模型精度。计算结果显示, 在轴向高度分别为 4、12、20m 处, 催化剂床层密度计算值与实际测量值高度吻合。对再生催化剂碳含量、再生催化剂温度、烟气温度及烟气摩尔组成等关键参数, 其计算值与实际值的相对误差均不超过 5%, 表明所建模型分析结论准确可靠。 [ABSTRACT FROM AUTHOR] |
