【摘要】：以天然气凝液脱轻烃工艺为例,提出了基于动态模拟的HAZOP分析方法,利用HYSYS动态模拟对HAZOP偏差进行量化分析,通过过程模拟所获得的偏差偏离正常值所达到具体量,有效解决传统HAZOP分析偏差的模糊性问题,且对工艺潜在的风险以及风险发生与否有一个更直观认识。并在传统HAZOP分析表的基础上提出了基于动态模拟结果的HAZOP分析表,增加了模拟结果分析及安全措施模拟验证等内容;首次提出了"安全域"这一概念,该概念指的是动态模拟时某一参数由初始值到达危险峰值的时间,这段时间的长短可以反映出某偏差造成事故的危险程度及可能性,为处理危险事故场景提供了时间的参考临界值,从而进一步提高HAZOP分析的准确性与可靠性,使HAZOP分析更加完善。
[Abstract]:Taking natural gas condensate desalination process as an example, a HAZOP analysis method based on dynamic simulation is proposed. The deviation of HAZOP is analyzed quantitatively by HYSYS dynamic simulation, and the deviation from normal value obtained by process simulation reaches a specific amount. The fuzziness of traditional HAZOP analysis deviation is solved effectively, and a more intuitive understanding of the process potential risk and risk occurrence or not is obtained. Based on the traditional HAZOP analysis table, a HAZOP analysis table based on dynamic simulation results is proposed. The analysis of simulation results and the simulation verification of safety measures are added, and the concept of "safety domain" is proposed for the first time, which refers to the time when a parameter reaches the dangerous peak value from the initial value in dynamic simulation. The length of the time can reflect the danger degree and possibility of the accident caused by a deviation, and provide the critical value of time reference for dealing with the dangerous accident scene, thus further improve the accuracy and reliability of HAZOP analysis. Make HAZOP analysis more perfect.
