先进控制技术在连续重整装置的应用

介绍了先进控制技术在中国石化镇海炼化分公司1.20 Mt/a连续重整装置上的应用情况。通过对装置现状的详细分析，确定了先进控制的控制目标和策略，并设计开发了相应的控制器和软仪表。先进控制系统投用后，装置关键控制指标的波动标准偏差降低30%以上，提高了装置平稳率，实现了设备能力和产品质量的卡边操作，达到了提高目标产品收率和装置节能降耗的目的，其中燃料气平均单耗下降4.44 m3/t（标准状态），年创经济效益约1 147万元。

THE APPLICATION OF ADVANCED PROCESS CONTROL TECHNOLOGY ON ONE CONTINUOUS CATALYTIC REFORMING UNIT

The application of the advanced process control (APC) technology on the 1.2 Mt/a CCR unit of SINOPEC Zhenhai Company was introduced. After performed a detailed analysis of the status of equipment in the CCR unit, the control objectives were laid out and the strategy was determined. Controllers and soft instrumentation were then designed and developed to meet these requirements. After commissioning said APC system, the fluctuation of the standard deviation of key control parameters in the CCR unit reduced more then 30%. The APC technology also contributed to high unit stability and maximized unit capacity with qualified product. The goal of improving product yield while saving energy consumption was achieved with the commissioning of APC technology. It was found that the average fuel gas consumption rate decreased 4.44 Nm3/t, indicating a cost-saving worth up to 11.47 million RMB.
