Abstract

In this paper, the procedure of determination, analysis and rectification of repeatable trips causes of off-gas compressors located in condensate stabilization unit of South Pars Gas Complex 2nd refinery, that have instrumentation and control system sources, are presented. Besides decreasing of production rate and increasing acid gas flaring, each trip results serious and inevitable damages on environment, human health, equipments and their accessories in consequent. Significant reduction in number of trips has been achieved by finding proper solutions for all mentioned problems and applying needed modifications that could be listed as changes in temperature transmitter settings, changing the types of them, upgrading Human Machine Interface, addition of new signals to PLC software to be shown in monitoring system and DCS for enhanced trip analysis and also correction of some control system program parts such as determination of First out alarm. In addition the above cases; security enhancement in the monitoring system is much considerable.

减少冷凝水稳定装置压缩机停机的方法

本文介绍了位于南帕尔斯天然气联合企业第二炼油厂冷凝液稳定装置中、具有仪表和控制系统源的废气压缩机重复跳闸原因的确定、分析和纠正程序。除了降低生产率和增加酸性气体燃烧外，每次跳闸都会对环境、人类健康、设备及其附件造成不可避免的严重损害。通过为所有上述问题找到适当的解决方案，并进行必要的修改，如改变温度变送器的设置、改变变送器的类型、升级人机界面、在 PLC 软件中添加新信号以显示在监控系统和 DCS 中以加强跳闸分析，以及修正控制系统程序的某些部分，如确定首次跳闸报警，从而显著减少了跳闸次数。除上述情况外，监控系统的安全性也有很大提高。
