摘要：

为预防连续式反应器在运行过程中因热失控而发生的爆炸事故,提出一种融合动态模拟与韧性评估的反应器爆炸事故防控方法。首先,基于反应器运行特性及热失控机制,明确温度、压力等关键工艺参数,系统识别潜在干扰事件;其次,利用Aspen Hysys软件开展动态模拟,分析不同干扰事件下反应器关键工艺参数时变特征,在此基础上,考虑工艺参数多维性与时变特征,基于最优最劣算法(BWM)构建工艺参数驱动的反应器系统韧性评估模型,综合评价反应器防爆韧性;最后,以乙烯与苯制乙苯连续式反应器为例,验证该方法的准确性和适用性。研究结果表明:相较于反应器压力和出口流量,反应器温度受进料温度阶跃变化的影响最为敏感;进料温度的阶跃变化会对反应器系统性能和韧性产生显著的非线性影响,当进料温度分别升高12.5%和62.5%时,反应器系统性能分别降至0.9和0.46,对应的系统韧性分别为0.88和0.82;通过提高反应器防爆韧性,可将关键工艺参数控制在安全阈值之内,从而预防爆炸事故发生。

Abstract:

To effectively prevent explosion accidents in continuous reactors due to thermal runaway during operation, this study proposed a reactor explosion accident prevention method that integrates dynamic simulation and resilience assessment. Firstly, based on the operating characteristics of the reactor and the mechanism of thermal runaway, key process parameters such as temperature and pressure were identified, and potential interference events are systematically recognized. Secondly, dynamic simulation was carried out using ASPEN HYSYS to analyze the time-varying characteristics of key process parameters under different interference events. On this basis, considering the multi-dimensional nature and time-varying characteristics of process parameters, a process parameter-driven resilience assessment model for the reactor system was constructed using the optimal-worst algorithm (BWM), and the overall resilience of the reactor system was evaluated. Finally, targeted resilience improvement strategies were proposed based on the assessment results, thereby preventing explosion accidents in continuous reactors. Taking the continuous reactor as an example, typical interference scenarios were simulated and resilience assessment was conducted to verify the accuracy and applicability of the method. The research results show that by coupling dynamic simulation with resilience assessment, the impact mechanism of interference events on the safety status of the reactor can be systematically revealed. By improving the system resilience, the key process parameters of the reactor can be controlled within the safety threshold, providing a theoretical basis and practical path for the transformation from passive response to active prevention in accident prevention.
