先进控制(APC)技术应用于炼化生产装置可提高操作平稳率、实现卡边操作、降低劳动强度、消除外部干扰、脱除装置瓶颈、提高装置运行水平。中国石化天津分公司已有4套炼化生产装置实现了先进过程控制,为全面提高企业生产装置竞争能力,在2号加氢裂化等7套装置上建设与应用APC技术,在项目建设与应用的过程中,摸索出一套TETA管理方法,即一个优秀团队(TEAM)、双引擎驱动(ENGINE)、三大层面的技术支撑(TECHNOLOGY)、四项工作目标(AIM)。TETA管理法创造了APC项目建设的最快纪录,7套装置从开工到投产仅用了16个月,每年可创造经济效益2377.5万元,并且提高了装置操作平稳率,关键被控变量标准偏差降低了21%~86.2%,控制器投用率达到98%~100%;实现了焦炭塔预热、换塔、大吹汽过程根据工况自动调整,从而减少了操作人员劳动强度。
The application of advanced control (APC) technology to refinery production equipment can improve the smoothness of operation, realize card edge operation, reduce labor intensity, eliminate external interference, remove device bottleneck and improve device operation level. China Petrochemical Tianjin Branch has 4 sets of refinery production facilities to achieve the advanced process control, in order to comprehensively improve the competitiveness of production facilities, in the No. 2 hydrocracking facilities such as 7 sets of APC technology and construction and application of the project construction and application A set of TETA management methods, namely TEAM, ENGINE, three levels of technical support and four working objectives (AIM) were explored. TETA Management Law has created the fastest APC project record, 7 sets of equipment from the start to put into operation only 16 months, 23.775 million yuan each year to create economic benefits, and improve the smooth operation of the device, the key controlled variable standard deviation Reduced by 21% -86.2%, and the dosage rate of the controller reached 98% -100%. The preheating of the coke drum, the change of tower, and the big blow-steaming process were automatically adjusted according to working conditions, thereby reducing the labor intensity of the operator.
