摘要:

为全面高效率分析与评价化工过程风险,设计开发基于符号有向图(SDG)与案例推理(CBR)的化工过程风险分析与评价辅助系统,并集成保护层分析(LOPA)和安全完整性等级(SIL)基础验算功能,实现风险的半定量化分析和评价。此外,利用CBR技术实现对化工过程历史案例经验的有效保存与复用,提高危险与可操作性分析(HAZOP)和评价辅助系统的使用功效。采用该系统开展丙烯氧化制取丙烯酸化工工艺风险评价,结果表明:该系统与企业自主风险评价的结果基本一致,具有良好的实用性和可靠性。SDG-CBR耦合推理机制突破传统HAZOP对人工经验的依赖,实现危险识别从定性到半定量转变,提高评估效率和准确性。

Abstract:

To comprehensively and efficiently analyze and evaluate chemical process risks, a risk analysis and evaluation auxiliary system for chemical processes was designed and developed based on SDG and CBR. The system was integrated with foundational verification functions for layer of protection analysis (LOPA) and safety integrity level (SIL), enabling semi-quantitative risk analysis and evaluation. Additionally, CBR technology was utilized to effectively preserve and reuse historical case experiences in chemical processes, thereby enhancing the efficacy of HAZOP and the auxiliary evaluation system. The system was applied to conduct a risk evaluation of the propylene oxidation to acrylic acid process. The results demonstrate that the system aligns closely with the independent risk evaluation outcomes of the enterprise, exhibiting strong practicality and reliability. The SDG-CBR coupling reasoning mechanism is verified to overcome the reliance of traditional HAZOP on manual experience, achieving a qualitative-to-semi-quantitative transformation in hazard identification while enhancing evaluation efficiency and accuracy.

Key words: signed directed graph (SDG), case-based reasoning (CBR), hazard and operability analysis (HAZOP), chemical process, risk assessment
