摘　　要：摘 要:选择了θ圆整归一方法应用于原油蒸馏过程稳态模型的计算。实验证明这种方法的应用提高了模型计算中迭代速度,可以达到加速收敛的效果,这种归一圆整的方法完全可以适应原油蒸馏常压塔具有多股进料、多股汽液侧线采出的特点。并可望应用于原油蒸馏过程动态模型的计算。本文给出了应用于不同平台的仿真结果。In this article, θ method is used in crude oil distillation model to accelerate iteration process in the calculation of steady state model. The application of this method in steady state model of crude distillation has proved to be efficient. It can accelerate the convergence process of steady state model of petroleum distillation. It adapted the main characters of petroleum distillation process well. It is promising that this method can also be used in dynamic model of crude oil distillation. The simulation results are given.

关 键 词：θ法、稳态模型、原油蒸馏
