摘要: 以国内某海上油田中心平台原油处理一级分离器(CEPA-V-2001A/B)为依托,建立符合实际情况的工艺泄压模型,用于单体设备和多体设备在堵塞工况下,紧急关断阀SDV 和安全泄压阀PSV 的泄放过程计算与分析。结果表明,单体一级分离器气相或油相出口发生堵塞时,系统压力均会超过SDV 联锁关断压力和PSV 设定压力,需考虑设置SDV和/或PSV安全保护装置;水相出口发生堵塞时,本由水相出口排出的水量在油相液位控制器的作用下,通过增大油相出口阀门开度实现油、水同时排出,不会引起系统的超压;对于给定的单体一级分离器,可选取口径为324.5mm 的G型PSV阀用于堵塞工况的泄压保护;当两分离器并联工作时,其中某一分离器的气相、油相或水相出口发生堵塞,不会引起系统超压。

Abstract: Based on the primary production separators (CEPAV2001A/B) of an offshore center platform in domestic, models, in line with actual production, are established. Key parameters in the separators and relief characteristics are investigated when choking accident occurs. Following conclusion is drawing: Firstly, when oil or gas outlet of CEPAV2001A is blocked, separator pressure will surpass the set point of SDV and PSV, and protection devices, such as SDV or PSV, should be taken into account. However, while the water outlet is choked, the pressure will not climb too high to protection; Secondly, according to simulation and comparison, a Gtype PSV with 324.5 mmdiameter is selected for protection under blocking accident; Lastly, equipping with two separators in parallel can ease, or eliminate the pressure climbing of the system. 
