前言由于催裂化装置有些参数不具备在线检测的条件,即使所有重要参数都能在线检测,没有一个最优控制的数学模型也是不行的,所以,很难在短期内实现全装置的最优闭环控制,因此,可以采用不同层次逐步实现最终目标,第一步实现数据采集和过程管理;第二步实现监测预报;第三步实现开环指导,之后实现某些回路的在线控制,最终实现优化闭环控制。最大程度的获得催化裂化装置的利润,必须要迅速准确地测出操作参数,原料量等值,在此基础上实 Preface Since some parameters of the catalytic cracking unit do not have the online detection conditions, even if all important parameters can be detected online, it is not feasible to have a mathematical model of optimal control. Therefore, it is very difficult to realize the optimal closed-loop control , So you can use different levels and gradually achieve the final goal, the first step to achieve data acquisition and process management; the second step to achieve monitoring and forecasting; the third step to achieve open-loop guidance, and then achieve some of the online control loop, and ultimately optimize the closed-loop control. To maximize the profitability of catalytic cracking unit, we must quickly and accurately measure the operating parameters, the amount of raw materials, etc., on the basis of this
