摘要
针对我国炼油厂FCC装置的现状,提出了模块式的再生器通用模型,并据此开发了相应的过程模拟系统.利用工业装置的现场操作标定数据对几种典型的FCC再生器进行了模拟计算,结果的总平均相对误差都在10%左右.
Despite the fact that various types of FCC regenerator are in commercial use, it is belived that they can be summed up into two typical regeneration processes: backmixing regeneration in fluidized bed and coke-burning regeneration under near gas transfer condition with the addition of mixing under various circumstances. A generalized model based on this concept is developed which consists three blocks, i.e. back-mixing model, coke burning model and a mix block. This modular general model is very simple and practical in use.The precision of this model is greater than that of a special purpose model.Its overall average relative error is about 10%.
