侧反应与精馏集成过程的故障动态特性模拟研究

针对甲苯氯化侧反应与精馏集成生产过程，在对实际生产过程合理简化与假设基础上，研制了该生产过程含控制策略的动态模拟系统。在动态模拟系统中合理设置引起反应能力与分离能力不匹配故障因素，如反应器进料配比失调、回流量过低和塔釜加热量不足等过程扰动，进行故障动态仿真研究。分析在故障扰动下整个系统的故障动态特性，获得有效的故障数据，解决了在实际生产装置上无法进行故障实验研究获取系统故障信息的难题。

Fault dynamic simulation for distillation process with side reactors

For the actual distillation process with side reactor, a dynamic simulation system including control system is developed based on reasonable simplifying and assumptions.Some typical fault disturbances which induced the dynamic imbalance between the separation capability and reaction capacity, such as the disturbance of unreasonable feed flow ratios for reactor, the disturbance of descended the reflux flow, the disturbance of insufficient steam heating for column bottom are introduced reasonably in the dynamic simulation system.The dynamic characteristics under the condition of above fault disturbances are simulated and researched deeply, then the virtual fault data is obtained.The problem which the fault information cann’t be gained by experimental research in the actual distillation process equipment is solved in this paper.
