碳捕集、利用与封存系统安全风险模拟研究

Safety Risk Simulation for CCUS Systems

碳捕集、利用与封存(CCUS)是实现区域碳中和目标的重要选择。然而,CCUS的工业应用及其供应链网络的延伸不可避免地增加了物质的流动和加工操作,造成潜在的安全风险问题。针对区域CCUS系统,提出了一个从碳排放源到碳汇的安全风险模拟模型。针对已有CCUS模块,基于ALOHA软件模拟区域CCUS系统事故影响范围,并从系统的角度模拟发生多米诺效应的极限距离。以山东省东营市为例,针对给定空间的CCUS系统部署,研究其各模块定量的安全风险影响范围并绘制风险地图。

Carbon capture,utilization,and sequestration(CCUS)is an important option for meeting national carbon neutrality targets.However,the application of CCUS on an industrial scale and the extension of supply chain networks inevitably increase the exchange of information and material flows,creating potential safety risk issues.This work proposed system modeling and safety risk assessment for integrated regional CCUS systems.Considering CCUS modules,ALOHA builds a regional CCUS system accident effect area simulation prediction model,and the limit distance of domino effect is simulated from the perspective of system.A CCUS system in Shandong Province is illustrated as a case study to analyze its safety risk.For the CCUS supply chain deployment in a given space,the quantitative safety risk effect area of each module is studied and a risk map is drawn.
