催化裂解制乙烯装置三机组全自动控制的应用

Application of Automation Control of Catalytical Cracking for Ethylene Installation Three Units

电机-主风机-烟机三机组是催化裂解(DCC)制乙烯装置中的核心设备,直接影响工艺装置的稳定运行和能耗,且操作难度高。介绍了主风机的工艺控制需求,通过分析主风机、烟机的运行特点,增加了主风机性能控制及烟机自动暖机、升速、并网控制,成功实现了主风机自动控制负荷、烟机一键启动,达到了预期的效果。相比手动操作,该功能更加高效、安全、可靠和人性化,为装置高效平稳运行提供有力保障。

The three units of electrical machinery-axial flow main fan-flue gas turbine are the core devices of catalytical cracking for ethylene installation.It directly influences the stable operation and energy consumption of the process installation with high operation difficulty.The process control requirements of the main fan are introduced,through analyzing the operation characteristics of main fan and flue gas turbine,the performance control of the main fan and the automatic warm-up,speed rise and grid-connected control of the flue gas turbine are added,the automatic load control of the main fan and the one-key start of the flue gas turbine are successfully realized,and the expected results are achieved.Compared with manual operation,the function is more efficient,safe,reliable and humanized,which provides a strong guarantee for the efficient and stable operation of the installation.
