摘要
高完整性保护系统(HIPS)作为消减火炬排放量的一种措施,介绍了HIPS的常见设置、安全完整性等级(SIL)要求和消减火炬排放量的原理。在确定HIPS起效后超压设备的泄放量时应综合考虑工艺流程、HIPS设定点等因素的影响,进行严谨的动态模拟分析。在确定全厂火炬系统HIPS消减方案时,应综合动态泄放研究、火炬系统失效概率计算等手段,在保障安全的前提下实现投资与收益的平衡。提出了HIPS在火炬排放量消减应用中常见的问题,以期对火炬系统的设计工作提供有价值的参考。
HIPS as a measure to mitigate total flare relief load, typical configurations and SIL requirements of HIPS are introduced as well as philosophies how HIPS can mitigate flare relief load. When determining the relief load of overpressure equipment after HIPS is activated, the effect of technological process and HIPS set point should be considered comprehensively, and rigorous dynamic simulation analysis should be conducted. When determining HIPS scheme of whole plant flare system, dynamic relief study and failure probability calculation of flare system should be integrated to balance investment and income on the premise of ensuring safety. Common problems in the applications of HIPS in flare relief load mitigations are put forward in order to provide valuable reference for the design of flare system.
