重油催化裂化装置全流程动态仿真培训系统

TRAINING SIMULATION SYSTEM FOR THE WHOLE PROCESS OF FLUID CATALYTIC CRACKING UNITP

应用机理分析，开发了重油催化裂化装置反应再生系统非线性状态空间模型，它包括了不完全再生过程特性的描述；运用非平衡级原理，直接计算塔器内部汽液两相传质、传热，建立了主分馏塔的动态数学模型；开发了计算机之间的内存数据直接通讯技术，提高了通讯速度；研制了２００万吨／年重油催化裂化装置全流程多模型ＤＣＳ动态仿真培训系统。

A nonlinear state space model for fluid catalytic cracking unitswas developed based on the technological principle. It includes a complete description of CO to CO 2 combustion kinetics in both full and partial CO combustion. Based on the transfer rate of mass and energy,a non-equilibrium stage dynamic model of main fractionator was presented. A new computer data communication technology, which directly communicates data between the server and PC memory, was used for DCS training simulator in FCCU (2.0 millions t/a).
