根据物料平衡、能量平衡和化学反应动力学原理，开发了催化重整装置的非线性动态数学模型，用二维拉氏变换及正交配制方法把分布参数模型转化为集中参数模型求解。仿真结果表明，模型的稳态结果与动态变化范围逼近实际装置。该模型可应用于炼油厂铂重整装置的开工、停工、正常操作及各种事故处理的动态模拟和仿真培训。 According to the principle of material balance, energy balance and chemical reaction kinetics, a nonlinear dynamic mathematical model of catalytic reforming unit is developed. The distribution parameter model is transformed into a centralized parameter model by two-dimensional Laplace transform and orthogonal formulating method. The simulation results show that the steady-state results of the model and the dynamic variation range approach the actual device. This model can be applied to the dynamic simulation and simulation training of the start-up, shutdown, normal operation and various accident treatment of the refinery platinum reformer.
