轻烃回收装置自控系统改造方案分析与设计

analysis and Design of Scheme for Reconstructing an Automatic Control System of Light Hydrocarbon Recovery Apparatus

针对宝浪油田联合站轻烃回收装置上的自动控制系统存在的问题,进行了分析与实践。通过改造硬件设备,增加天然气外输自动控制方案,修改快速切断阀的控制策略,改变低温分离器控制阀的安装位置,采取电源工作地与系统屏蔽接地技术以及UPS电源冗余等技术措施,使得改造后的控制系统达到很好的运行效果。

In allusion to the problems existed in an automac control system of light hydrocarbon recovery apparatus in a joint station of Baolang Oifield,the problems were analyzed and practised.By reconstructing the apparatus.A scheme for gas transfer automatic control was estalished,the control strategy of rapid break of valves was modified.A position for setting a control valve of low temperature and sepration was changed.By using the techniques of power resource working place and system screen grounding,good effect is obtained after reconstruction.
