摘要
碳捕集、利用与封存技术是应对气候变化减排二氧化碳的有效技术之一。考虑到二氧化碳泄露风险的不确定性,用模糊语言来评价二氧化碳泄露的各种风险因素,将模糊集和证据理论相结合进行二氧化碳地质封存项目安全风险评价。利用Jousselme距离确定专家权重,并对冲突证据进行修正,再采用Dempster组合规则融合不确定证据信息。通过严格的风险评价程序,从而选择理想的二氧化碳封存场地。
Carbon dioxide capture,utilization and storage technologies are one of the effective technologies to reduce greenhouse gas atmospheric emissions in order to reply for climate change. Considering the uncertainty of the CO2 leakage,fuzzy linguistic languages given by the experts are used to evaluate the risk factors of CO2 leakage,the combination of the fuzzy set and evidence theory is proposed to make risk assessment. The Jousselme distance is used to determine the weight of experts,then the Dempster combination rule is used to fuse the uncertain conflicting evidences considering the experts weights. Through the strict safety risk evaluation procedure,the best geological storage site can be selected.
