摘要：提出了乙烯氧化反应器定态和动态优化相结合的优化策略。为降低优化方法对操作经验的过分依赖,优化时采用一维拟均相反应器模型和广义幂函数型失活动力学模型。为了顾及催化剂失活的动态效应和使多优化变量的乙烯氧化反应器的动态优化得以实现,将对床层温度敏感的两个操作变量反应温度和二氯乙烷含量作为动态优化变量。开发了将模拟、参数估计和优化等任务集成的乙烯氧化反应器优化软件,使定态与动态优化相结合的优化策略易于实施。
Combination of steady state optimization with dynamic state optimization was presented to optimize ethylene epoxidation reactor. One-dimensional pseudohomogeneous model for reactor and generalized power function for deactivation kinetics were adopted to reduce the dependence of optimization on operational experience. Optimizing variables, which were not sensitive to reactor temperature, were determined by steady-state optimization, while water temperature and dichloroethane (EDC) concentration were determined by dynamic optimization, in order to pay regard to dynamic effect of catalyst deactivation and make dynamic optimization easy to implement. A package of simulation and optimization was developed to integrate simulation, parameter estimation and optimization to facilitate application of optimization to industrial reactor.
