【摘要】：为了研究基于风险的检验(RBI)中燃烧、爆炸后果分析方法在实际应用中的效果,以API 581为基础,介绍了Level 1分析法、Level 2分析法及分析流程;然后,以油气分离器为例,根据API 581推荐的Level 1分析法编写VB程序,计算后果面积,采用PHAST软件计算Level 2分析法的后果面积;对比分析两种方法的计算结果,以及二者计算准确性的主要影响因素。研究结果表明:Level 1法比Level 2法简单,但其计算准确性较低;后果面积计算准确性的主要影响因素包括潜在泄漏质量、能量调整系数和液相后果计算面积公式选用等;应用时应兼顾两种方法的计算精度和经济效益,并选取合适的分析方法。
[Abstract]:In order to study the effect of the method of combustion and explosion consequence analysis in practical application, based on API 581, the Level 1 analysis method is introduced. Level 2 analysis and analysis process; Then, taking the oil and gas separator as an example, the VB program is compiled according to the Level 1 analysis method recommended by API 581, and the consequence area is calculated. The consequence area of Level 2 analysis was calculated by PHAST software. The results of the two methods are compared and analyzed, and the main factors affecting the accuracy of the two methods are analyzed. The results show that the weight level 1 method is simpler than the Level 2 method, but its calculation accuracy is lower. The main factors affecting the accuracy of the calculation of the consequence area include the potential leakage quality, the energy adjustment coefficient and the choice of the formula for calculating the area of the liquid consequence. The calculation accuracy and economic benefit of the two methods should be taken into account in application, and appropriate analytical methods should be selected.
