摘要
炼油工业生产过程是石化工业的起点,结合常减压蒸馏装置的生产工艺特点,构建了基于Mantra软件的常压塔切割点的先进控制仿真平台,并对不同控制策略的控制效果进行了比较。首先利用Visual Basic软件搭建了常压塔过程关键变量的控制模型和OPC数据通讯接口;然后利用Mantra中的先进控制模块MMC,PID模块和逻辑运算模块等搭建常压塔的切割点的多变量预测控制平台。控制平台可以通过OPC服务器连接常压塔控制模型,实现闭环控制,实现常压塔的切割点的有效控制。最后,对MMC和PID控制的控制效果和控制曲线进行了比较和分析,说明了基于MMC的切割点控制系统的优势与不足。
Oil refining industry production process is the starting point of the petrochemical industry, this paper combining with the characteristics of production technology of atmospheric and vacuum distillation unit, uses the Mantra software to build the advanced con- trol simulation platform of crude distillation tower cutting point, and the control effect of different control strategies are compared. This paper uses the Visual Basic software to build control model of crude distillation tower process＇s key variable and OPC data communica- tion interface; then by using the MMC advanced control module, PID module and logic module in Mantra to build muhivariable predic- tive control platform of the crude distillation tower cutting point. The control platform can connect crude distillation tower Control model through OPC server, to achieve closed-loop control and effectively control the cutting point of crude distillation tower. Finally, the control effect of MMC and PID control and the control curve are analyzed and compared, to explain the advantages and disadvantages of cutting control system based on MMC.
