简述了某FCC汽油选择性加氢脱硫装置工艺流程,根据催化剂厂家提供的设计基础数据包,利用工艺流程模拟软件对该装置进行了全流程模拟计算。模拟流程过程参数和模拟得到的汽油产品性质与数据包中数据几乎一致,误差在工程设计允许范围之内,所以,利用文中所述方法进行全流程模拟,在工程设计中是可行的。 The process flow of a FCC gasoline selective hydrodesulfurization unit is briefly described. Based on the design basis data package provided by the catalyst manufacturer, the entire process simulation calculation is carried out using the process flow simulation software. The parameters of the simulation process and the nature of the simulated gasoline product are almost the same as the data in the data package. The error is within the allowable range of engineering design. Therefore, it is feasible to carry out whole process simulation using the method described in this article.
