Abstract This study introduces a new approach for designing a flare network system that ensures economic feasibility and safety using dynamic simulation analysis with the gPROMS ProcessBuilder software. A case of “separator outlet blocked discharge” was selected as a pressure-relief scenario based on the American Petroleum Institute Standard 521, and design data from a previous offshore project were used. As the main process and flare network system were dynamically simulated, the effects of the pressure, temperature, and liquid-level changes in the vessel on the opening of the pressure safety valve (PSV) were analyzed. Then, dynamic simulation results, including those for the flare load, PSV back pressure, and Mach number, were compared with those obtained from a steady-state model employing the Aspen Flare System Analyzer. Lastly, the sizes of the PSVs, branch lines, and main headers were optimized to minimize the overall capital costs and ensure the safety of the flare network system. This methodology can be applied to all existing and newly designed flare network system to enhance safety and reduce capital costs.

海上装置上部工艺火炬网络系统动态分析与优化

摘要 本研究介绍了一种设计火炬网络系统的新方法，使用 gPROMS ProcessBuilder 软件进行动态模拟分析，以确保经济可行性和安全性。根据美国石油学会标准 521，选择了“分离器出口堵塞排放”的案例作为泄压方案，并使用了先前海上项目的设计数据。通过对主过程和火炬网络系统进行动态模拟，分析了容器内压力、温度和液位变化对压力安全阀（PSV）开启的影响。然后，将动态模拟结果（包括火炬载荷、PSV 背压和马赫数）与从采用 Aspen Flare System Analyzer 的稳态模型获得的结果进行比较。最后，PSV、支线和主集管的尺寸进行了优化，以最大限度地降低整体资本成本并确保火炬网络系统的安全。这种方法可以应用于所有现有和新设计的火炬网络系统，以提高安全性并降低资本成本。
